a smooth wooden 40.0 n block is placed on a smooth wooden table. a force of 14.0 n is required to keep the block moving at constant velocity. what is the coefficient of sliding friction between the block and the table top? if a 20.0 n brick is placed on top of the wooden block, what force will be required to keep the block and brick moving at constant velocity?
The coefficient of sliding friction between the block and the table top is 0.35. The force will be required to keep the block and brick moving at constant velocity is 21 N.
The coefficient of sliding friction (μ_s) is given by the ratio of the force of friction to the normal force.
For the wooden block on the table top:
Fs = μs * N
where
Fs = 14.0 N (force required to keep the block moving at constant velocity)
N = 40.0 N (normal force on the block)
So
μs = Fs / N = 14.0 N / 40.0 N = 0.35
When a 20.0 N brick is placed on top of the wooden block, the normal force on the block increases to 60.0 N (40.0 N + 20.0 N).
The force required to keep the block and brick moving at constant velocity can be calculated using the same formula as above:
Fs = μs * N

The value of the universal gravitational constant is 6.672 × 10−11 N · m^2 /kg^2.
Answer in units of N.
2 ) Leaving the distance between the 141 kg and the 494 kg masses fixed, at what distance from the 494 kg mass (other than infinitely remote ones) does the 74.8 kg mass experience a net force of zero?
Answer in units of m.
( 1) The net gravitational force between the 74.8 kg mass is 8.09 x 10⁻⁵ N.
( 2) The distance from the from the 494 kg mass where the middle mass experiences net zero force is 0.258 m.
What is net gravitational force on the middle mass?The net gravitational force acting on the middle mass is calculated by applying Newton's law of universal gravitation as shown below.
F = ( GmM ) / ( R² )
where;
G is universal gravitation constantm is the mass of the middle massM is the mass of the first massR is the distance of separation between the two massesThe force between the first mass and the middle mass is calculated as;
F' = ( 6.672 x 10⁻¹¹ x 141 x 74.8 ) / ( 0.198² )
F' = 1.8 x 10⁻⁵ N
The force between the third mass and the middle mass is calculated as;
F'' = ( 6.672 x 10⁻¹¹ x 494 x 74.8 ) / ( 0.198² )
F'' = 6.29 x 10⁻⁵ N
The net gravitational force on the middle mass;
F (net) = 6.29 x 10⁻⁵ N + 1.8 x 10⁻⁵ N
F ( net ) = 8.09 x 10⁻⁵ N
Let the distance of zero net force from the 141 kg mass = d.
then the distance from the 494 kg mass = 0.396 m - d
F' = ( 6.672 x 10⁻¹¹ x 141 x 74.8 ) / ( d² )
F' = 0.704 x 10⁻⁶ / d²
F'' = ( 6.672 x 10⁻¹¹ x 494 x 74.8 ) / ( 0.396 - d )²
F'' = 2.47 x 10⁻⁶ / ( 0.396 - d )²
for zero net force, the two forces must be equal
0.704 x 10⁻⁶ / d² = 2.47 x 10⁻⁶ / ( 0.396 - d )²
0.704 (0.396 - d )² = 2.47d²
(0.396 - d )² = ( 2.47d² ) / ( 0.704 )
(0.396 - d )² = 3.51d²
0.396 - d = √ ( 3.51d² )
0.396 - d = 1.87d
1.87d + d = 0.396
d (1.87 + 1) = 0.396
d (2.87) = 0.396
d = 0.396 / 2.87

The speed of the object at the height of (1/2)hmax is expressed in terms of vvv and ggg, without using the value of g and h.
What does the word "speed" mean?Speed is what it means. the speed at which an object's location changes in any direction. The distance traveled about relation to the time it took to travel that distance is how speed is defined. Given that it just has a direction and no magnitude, speed is a scalar number.
How can we determined this?The speed of the object at the height of (1/2)hmax can be represented by the equation:
Speed = sqrt(2gh)
Where:
g = acceleration due to gravity
h = height
At the height of (1/2)hmax, the object has reached its maximum height and its speed is at its minimum, known as the "top speed." At this point, the object's vertical velocity (vvv) is equal to zero and its kinetic energy is equal to its potential energy, so we can write:
1/2mvvv^2 = mgh
Where:
m = mass of the object
By substituting the first equation into the second equation, we get:
1/2m(sqrt(2gh))^2 = mgh
Simplifying this equation, we get:
g = vvv^2 / 2h
Now, we can substitute the value of g back into the first equation:
Speed = sqrt(2gh) = sqrt(2 * (vvv^2 / 2h) * (1/2)hmax)
So, the speed of the object at the height of (1/2)hmax is:
Speed = sqrt(vvv^2 / 2)

It is a two dimensional representation of an object which appears to be the same distance away from the lens as the original object. It is formed by the convergence of light rays that are not actually present, but seem to be originating from the image. Virtual images can be viewed on a screen or projected onto a wall. Virtual images cannot be projected onto a surface for viewing.
When you stand in front of it, the light from the object that you are looking at reflects off the mirror and creates an image of the object in the mirror. This is because light travels in straight lines and when it meets the mirror it bounces off it in the same direction.
When you are standing close to the mirror, the image of the object in the mirror is upright and appears to be the same height as the original object. This is because the light from the object is reflected off the mirror and reaches your eyes in a straight line. As you move away from the mirror, the distance between the object and the mirror increases and the light is no longer traveling in a straight line. The light is now traveling at an angle and this causes the image to appear tilted in the mirror. This tilt causes the image to appear shorter than the original object.

A horizontal force acts on a block sliding on a horizontal surface. the force of kinetic friction between the block and the surface is 0.5 n. if the direction of the applied force is reversed, which is true?
If the direction of the applied force is reversed on a block sliding on a horizontal surface, the force of kinetic friction between the block and the surface will also be reversed.
The force of kinetic friction will now act in the opposite direction of the applied force, and its magnitude will remain the same (0.5 N). As a result, the net force acting on the block will be the difference between the applied force and the force of kinetic friction, which will determine the block's acceleration. The block will slow down and eventually stop moving, as the force of kinetic friction will be greater than the applied force in this case.

We know that the work-energy theorem states that the change in energy (in this case, kinetic energy) is equal to the work done on a system.
what is energy ?
Energy is the capacity to do work. It exists in many forms, such as kinetic, potential, thermal, electrical, chemical, nuclear, and mechanical energy. Kinetic energy is energy that is in motion, such as a moving car or the wind. Potential energy is energy that is stored, such as the energy stored in a stretched rubber band or a raised weight.
Thermal energy is the energy of moving molecules, such as the energy in hot water or in the air. Electrical energy is energy associated with the movement of electrons. Chemical energy is the energy stored in the bonds of atoms and molecules. Nuclear energy is energy stored in the nucleus of an atom. Mechanical energy is energy associated with the motion and position of an object.
