Question

what is the change of momentum of a car weighing 1500 kg when it's speeds increase from 36km/h 72 km/h uniformly?​

Answer 1

Answer:

The change in momentum of a car weighing 1500 kg when its speed increases from 36 km/h to 72 km/h =30000 kg.

Answer 2

Answer:- 15000kg.m/s

Explanation:

Mass of car = 1500kg

Velocity (v1) = 36km/hr=10m/s

=>Momentum (p1) = 1500×10 = 15000kg.m/s

Velocity (v2) = 72km/hr=20m/s

Momentum (p2) = 1500×20 =30000kg.m/s

Change in momentum = (p2 − p1)

= (30000 − 15000)

= 15000kg.m/s

Have a good day :)
