In which of the following situations is the kinetic energy of the object decreasing?

Answers

Answer 1

Answer:

baseball heading up

Explanation:

everything else constant or gaining

Answer 2

The kinetic energy of the baseball, which is heading upward after being thrown at an angle, is decreasing. Hence, option (C) is correct.

What is kinetic energy?

According to the definition of kinetic energy in physics, it is the amount of work that an item may accomplish while in motion. As a scalar quantity, kinetic energy can only be fully defined by its magnitude.

Mathematically, kinetic energy of an object is given by: E = 1/2 ×mv².

Where: m = mass of the object and v = speed of the object.

When  a baseball is heading upward after being thrown at an angle, its speed decreases as the acceleration due to gravity acts downwards. Hence, the kinetic energy of the baseball, which is heading upward after being thrown at an angle, is decreasing. Hence, option (C) is correct.

Answers

Answer:

d = - 10 [m]

Explanation:

We must remember that speed is defined as the relationship between the displacement in a given time. In this way, we can propose the following equation.

[tex]v = d/t[/tex]

where:

v = velocity = 2 [m/s]

d = displacement [m]

t = time = 5 [s]

A 0.56 kg model rocket produces 53 newtons of upward thrust as it shoots upward off the launch pad. With what acceleration meters per second-squared does the rocket launch?

Answers

resultant force = thrust – weight

acceleration = resultant force (newtons, N) divided by mass (kilograms, kg).

Acceleration = resultant force divided by mass

53N/0.56

=94.64 approximately 95

= 95m/s^2

This means that, every second, the speed of the rocket increases by 95m/s2

the S.I unit of Acceleration is meter per second square.

The acceleration in meters per second squared that the rocket launch is 94.64m/s²

According to Newton's second law, the formula for calculating the force acting on a body is expressed as;

F = ma

F is the applied force

m is the mass of the rocket

a is the acceleration of the rocket

Given the following parameters

Mass = 0.56kg

Force = 53N

Substitute the given parameters into the formula as shown:

F = ma

a = F/m

a = 53/0.56

a = 94.64m/s²

Hence the acceleration in meters per second-squared that the rocket launch is 94.64m/s²

A bicyclist with a mass of 50 kg is traveling at a rate of 30 m/s. It accelerates to a rate of 50 m/s in 5 seconds. What is the net force acting on the bicycle?

Answers

Answer:

200 N

Explanation:

There is only two needed factors in play here; the mass and acceleration

According to Newton's 2nd Law: F = m*a

Now Acceleration is Velocity over Time, so we have another factor in play: Acceleration = 50-30/5 = 20/5 = 4m/s^2

Net force = (50 kg)(4 m/s^2) = 50*4 = 200 Newtons

You are pushing a box toward your friend with a force of 15 N, and your friend is pushing the box toward you with a force of 30 N. What is the net force? What direction will the box move (toward you or toward your friend)?

Answers

Answer:

A. Net force is 15 N.

B. The answer is given below.

Explanation:

The following data were obtained from the question:

Force applied by you (Fᵧ) = 15 N

Force applied by your friend (Fբ) = 30 NForce applied by you (Fᵧ) = 15 N

Force applied by your friend (Fբ) = 30 N

Net force (Fₙ) =?

A. Determination of the net force.

Force applied by you (Fᵧ) = 15 N

Force applied by your friend (Fբ) = 30 N

Net force (Fₙ) =?

Fₙ = Fբ – Fᵧ

Fₙ = 30 – 15

Fₙ = 15 N

Thus, the net force acting on the box is 15 N.

B. From the question given above, we can conclude that the box will move towards you because the force applied by your friend is greater than yours.
