A scoters is moving with velocity 25 m/ sec and takes 5 sec to stop after brake is applied . If mass of scotter along with rider is 180 kg find change in momentum.

Open in App

Solution

U = 25m/s, v = 0, t = 5 s, m = 180 kg

pi = mu = 180 x 25
4500 kg m / s
pf = my
= 180 x 0
= 0 kgm /s
pf - pi = 0 - 4500
= -4500 kg m / s

Hence, the change in momentum is -4500 kg m/s.
