Question

calculate the momentum of the mass =400kg , velocity=40m/s and =mass 1000kg, velocity 40 m/s​

Answer 1

Explanation:

Given that,

Mass m=1000kg

Speed v

1

=36km/h=10m/s

Speed v

2

=108km/h=30m/s

We know that,

The change in momentum

ΔP=m(Δv)

ΔP=m×(v

2

)

ΔP=1000×(30−10)

ΔP=2×10

kgm/s

Hence, the change in momentum is 2×10
