Question

Same force acts on two bodies of different masses 3 kg and
5 kg initially at rest. The ratio of times required to acquire
same final velocity is​

Answer 1

Answer:

3/5

Explanation:

Same force is acting on both the bodies of mass 3kg and 5kg. Let time taken by both to acquire same final velocities be t1 and t2 respectively.

F1=F2

m1*a1=m2*a2

3(a1)=5*(a2)

3(v-u)/t1 = 5(v-u)/t2

since final velocities are same and initial velocity is zero,

3v/t1=5v/t2

3v/5v=t1/t2

t1/t2=3/5
