The `K.E.` acquired by a mass `m` in travelling a certain distance `d`, starting from rest, under the action of a constant force is directly propotional to

A

directly proportional to m

B

directly proportional to `sqrtm`

C

inverserly proportional to `sqrtm`

D

independent of m

Text Solution

Verified by Experts

The correct Answer is:
D

(d) `K_(2)-K_(1) = W =Fs`
`K_(2)-0=Fs`
K is independent of m. `" "`(Force is constant)
