Question

Two balls A and B of masses ‘m’ and ‘2m’ are in motion with velocities ‘2v’ and ‘v’ respectively. Compare their

a)Inertia

b)Momentum

c)Force needed to stop them in same time​

Answer 1

Answer:

hey mate here is ur ans

Explanation:

1.inertia of B is more than A because mass of B is more

2.momentum become same

for A,p = m×v = m×2v = 2mv

for B, p = m×v = 2m×v = 2mv

3. force needed to stop is same

acc to newton 2nd law force is rate of change of momemtum

momentum is same so force become also same

time is same in both case

hope it help u
