Question

A body of mass 5 kg undergoes a change in speed
from 20 m s-1 to 0.20 m s-1. The momentum

Answer 1

Hey mate here is your answer :

Answer:- mass = 5 kg

final velocity= 0.20 ms-1

Initial velocity=20 ms-1

change in momentum = mv - mu

(5kg × 0.20ms-1) - (5kg × 20ms-1)

1kg.ms-1 - 100kg.ms-1

-100kg.ms-1

momentum = mass × velocity

p = m × v

p = 5kg × -100ms-1

p = -500kg.ms-1
