Question

a loaded lorry of mass 12000 kg moves with a velocity of 12 m/s.Its velocity becomes 10 m/s after 5 seconds.
a) What is the initial momentum and what is the final momentum?
b) What is the change in momentum?
c) What is the rate of momentum?​

Answer 1

Answer:

initial momentum =mu

=12000×12=144000 kg m/s

Final momentum =mv

=12000×10=120000 kg m/s
