The kinetic energy, K, of an object varies jointly with its mass, m, and the square of its velocity, v. The mass of an object stays the same, but the velocity of the object is halved. How is the kinetic energy of the object affected? The kinetic energy is quartered. The kinetic energy is halved. The kinetic energy is doubled. The kinetic energy is quadrupled.

Answer:

the answer is A

Step-by-step explanation:

I took the test

The kinetic energy of the object is affected in that; The kinetic energy is quartered.

How to Solve Kinetic Energy Problems?

We are told that  kinetic energy, K, of an object varies jointly with its mass, m, and the square of its velocity, v. Thus;

K = mv²

Now, mass is same but velocity halved. Thus, we now have;

K = m(v/2)²

K = ¹/₄mv²

Thus, the kinetic energy is quartered.
