The kinetic energy acquired by a mass m in travelling a certain distance d, starting from rest, under the action of a constant force is directly

Question 1

The kinetic energy acquired by a mass m in travelling a certain distance d, starting from rest, under the action of a constant force is directly proportional to

(A) √m

(B) independent of m.

(C) 1/√m.

(D) m.

Question 2

Answer is (B) independent of m.

K.E = (1/2) mν2, & ν2 = 2ax = 2(F/m)x.

Hence K.E = Fx
