Question

A loaded lorry of mass 1500 kg moves with a velocity of 12 m/s. Within a small interval
of the time, the velocity becomes 10 m/s.
a) What is the initial momentum of the lorry?
b) What is its final momentum?
c) What is the change in momentum?

Answer 1

Explanation:

initial momentum = 18000kg.m/s

final momentum = 15000kg.m/s

change in momentum = final momentum - initial momentum .

15000-18000=-3000kg.m/s

change in momentum is -3000kg.m/s
