Question

a car of mass 1000 kilogram is moving with a velocity of 72 km per hour find its momentum​

Answer 1

the formula is P=MV

SO THAT P=1000*72

                  =72000Kgm/s

                   

                p= 1000kg *72km/hr (72*1000m/3600s)

                p= 1000kg * 20m/s

                p = 20000kgm/s or N/s

Answer 2

M=1000 kg

V=72 km/h

     =72×1000÷3600

     =20 m/s

P=?

As we already know that,

Momentum is the product of mass and velocity.

∴ P=m×v

⇒P= 1000 × 20

⇒P= 20,000 kg.m/s

∴The momentum of the car is 20,000 kg.m/s

I hope you can understand my explanation........
