Question

6.) An object of mass, m is
moving with a constant velocity, v. How much work should be done
on the object in order to bring the object to rest?​

Answer 1

Step-by-step explanation:

since the object is moving it would acquire kinetic energy

K.E = 1/2mv^2

therefore to bring the object to rest we need to apply

- 1/2mv^2 amount of work
