Question

A car of mass lookg moving with
sppeed gokm/hr falten seconds find
its momentum​

Answer 1

Answer:

Answer

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

−v

1

)

ΔP=1000×(30−10)

ΔP=2×10

4

kgm/s

Hence, the change in momentum is 2×10

4

kgm/s
