Question

change in momentum when a car weighting 700kg change its speed from 100 m/s to 200 m)/s
​

Answer 1

Initial velocity (u) = 100m/s

Final velocity (v) = 200m/s

Mass (m) = 700kg

We know that :-

Momentum = m(v-u)

= 700(200-100)

= 700×100

Momentum = 70000kgm/s

The momentum of a car of mass 700kg having initial velocity 100m/s and final velocity 200m/s is 70000kgm/s.
