Question

What is a change in momentum of a car weighting 1500 kg when its speed increasing from 36 kg/h to 72 kg/h uniformly

Answer 1

Answer:

15000 kg m s^-1

Explanation:

Change in momentum Is given by:

mv- mu

= 1500kg*72km h^-1 - 1500kg*36 km h^-1

=1500kg* 20m s^-1 - 1500kg* 10 m s^-1

= (30000-15000)kg m s^-1

=15000 kg m s-1
