a piano hangs from a steel cable. as it s lowered from a third- floor apartment to the groundt,he work done on the piano by the cable is (a) positive; (b)negative; (c) zero; or (d) it cannot be determined without more information
The correct option is option B.
For this exercise we must use the work definition
W = F. s
Where the bold characters indicate vectors and the point is the scalar producer
W = F s cos θ
Where θ is the angles between force and displacement.
Here, in this case, the cable creates an upward tension and with the piano going down the angle between them is 180º so the work of the cable on the piano is negative.
The evade has a downward force, its weight so the force goes down and the displacement goes down, as both are in the same direction the work is positive.
Therefore, the cable does negative work on the piano and piano does positive work on the cable and we can say work done on the piano by the cable is negative.

a 62.6 kg runner has a speed of 5.10 m/s at one instant during a long-distance event.hint(a)what is the runner's kinetic energy at this instant (in j)?814.11correct: your answer is correct.j(b)how much net work (in j) is required to triple his speed?
a)The runner's kinetic energy at the given instant is 814.11Joules b)net work required to triple his speed is 6653.361Jolues
Mechanical energy is divided into two parts- one kinetic energy and second one is potential energy.
a) The kinetic energy is given by the following expression =(1/2)mv² where m is the mass of the body and v is the velocity of the body.
Now, we have runner mass as 62.5kg and speed as 5.10m/sec
So, after putting in the formula we get,
K.E=(1/2)×62.6×(5.10)²
=>K.E.=31.3×(26.01)
=>K.E=814.11Joules.
b)According to the definition of work energy theorem, work done on the body is equal to change in kinetic energy of the body
W=ΔK.E
When velocity is tripled, final kinetic energy(KE₂)=(1/2)×62.6×(3×5.10)²
=>KE₂=31.3×9×26.01
=>KE₂=7467.471Jolues.
Initial kinetic energy(KE₁)=814.11Joules.
So, net work required=KE₂-(KE₁)
=>W=7467.471-814.11
=>W=6653.361Jolues
Hence, a)kinetic energy is 814.11Joules and b)net work required is 6653.361Jolues.

A 120 kg hoop rolls along a horizontal floor so that the hoop's center of mass has a speed of 0.180 m/s. How much work must be done on the hoop to stop it?
___ J
The work that must be done on the hoop to stop it is calculated to be -3.888 J.
As the mass of the hoop is 120 kg and the hoop's center of mass has a speed of 0.180 m/s, the rotational inertia can be given as follows;
I= mr^2
I=120r^2
The kinetic energy of hoop = Linear kinetic energy + Rotational kinetic energy
K= (1/2mv^2) + (1/2Iw^2)
But; w= (v/r)^2
K= (1/2mv^2) + (1/2×120r^2(v/r)^2)
K = (1/2×120×0.180^2) + (1/2×120×0.180^2)
K = 3.888 J
To stop the hoop, its final kinetic energy must be 0, therefore;
Work done = Kfinal-Kinitial = 0 - 3.888
W= -3.888 J
Hence, -3.888 J of work must be done to stop the hoop.

centripetal acceleration=v²/r
centripetal acceleration=25/2
centripetal acceleration=12.5 m/s²
The speed at which a body rotates around a circle is known as centripetal acceleration. When a body travels in a circle, its direction is constantly changing, which results in a change in velocity, which generates an acceleration because velocity is a vector quantity (i.e., it contains both a magnitude, the speed, and a direction). The acceleration is directed radially toward the center of the circle. The value of the centripetal acceleration, symbolized by the letter ac, is equal to the square of the body's speed along the curve divided by the circle's radius. This is sometimes referred to as the equation ac = v2/r. Meters per second squared are used to measure centripetal acceleration.

What is initial velocity?
A physical system's behaviour in terms of the its motion is described using equations of motion. The equations are relationships between different terms and quantities. There are primarily three equations of motion, also known as the laws of constant acceleration, that apply when there is uniform acceleration. Any object subject to forces will accelerate. The object's velocity changes as a result of this acceleration. As a result, the initial velocity is indeed the object's speed before the change brought on by acceleration. The velocity will become the final velocity after the object has been accelerating for a while.
Her speed at the bottom of the arc would depend on the magnitude of the initial velocity and the angle she is swinging out to.
Assuming that the initial velocity is constant, the speed at the bottom of the arc can be calculated using the equation:
v = v0 * cos(θ)
where v0 is the initial velocity and θ is the swing angle.
In this case, v0 is the initial velocity and θ is 45°, so the speed at the bottom of the arc would be:

Answer: 2.67 m/s2
Explanation:
W = mg = (22.4 kg)(9.8 m/s2) = 219.52 N
Wx = (219.52 N)(sin 22) = 82.2 N
Wy = (219.52 N) (cos 22) = 203.5 N
Wy = N (normal force on the block) = 203.5 N
Ff (force of friction) = (coeff. friction)(N) = (0.11)(203.5 N) = 22.4 N
Sum the forces in the x-direction (direction of motion down the ramp):
Fnet = Wx - Ff = 82.2 N - 22.4 N = 59.8 N
a = F/m = 59.8 N / 22.4 kg = 2.7 m/s2

Here we have to find the net magnetic force per meter.
Using dB= μi sinФ/ 4π r²dx the force on say, wire 1 (the wire at the upper left of the figure) is along the diagonal (pointing toward wire 3, which is at the lower right). Only the forces (or their components) along the diagonal direction contribute. With θ=45°, we find the force per unit meter on wire 1 to be
F1 =∣ F 12 + F 13 + F 14∣=2F 12 cosθ+F 13=2( μi²/ 2p ia)cos45° + μi² / 2√2πa
= 3 / 2√2π (μi²/a)
=3/ 2√2 π ( 4π × [tex]10 ^{-7}[/tex] T.m / A ( 15.0A)² / (8.50 ×[tex]10^{-2}[/tex]m)
= 1.12 × [tex]10^{-3}[/tex] N/m
The direction of F1 is along r = (î = j) / √2.
In unit-vector notation, we have
F1 = ( 1.12 ×[tex]10^{-3}[/tex]N/m) / √2 (i - j)
= ( 7.94 × [tex]10^{-4}[/tex]N/m) i + ( -7.94 × [tex]10^{-4}[/tex]N/m) j
Therefore the net force is ( 7.94 ×[tex]10^{-4}[/tex]N/m)i + (-7.94 × [tex]10^{-4}[/tex]N/m)

The free-fall acceleration at the surface of planet 1 is 26m/s^2 . The radius and the mass of planet 2 are twice those of planet 1. What is on planet 2?
The acceleration on planet 2 is 13 m/s².
Acceleration is the rate of change of the velocity of an item with appreciation to time. Accelerations are vector portions. The orientation of an item's acceleration is given by the orientation of the net pressure appearing on that object.
Calculation:-
The acceleration of gravity near the surface of a planet is:
g = MG / R²
For planet 1, g = 26 m/s^2.
The gravity on planet 2 in terms of the mass and radius of planet 1 is:
g = (2M)G / (2R^2)
g = 1/2 MG / R²
Since MG/R² = 26 m/s², then:
g = 13 m/s²
Acceleration is the charge at which velocity modifications with time, in terms of each speed and route. A factor or an object moving in a straight line is accelerated if it quickens or slows down. movement on a circle is extended despite the fact that the rate is consistent because the course is continually changing.
