Question

A car of mass 1000 kg is moving with a velocity of 18 km/h.What is the momentum of the car?​

Answer 1

Answer:

Momentum = m×v

where, m = mass of body

and, v = velocity of body

so,

momentum of given ques. = 1000 × 18 = 18000 kg-km/hr = 5000 kg-m/sec

Mark as Brainliest, it really motivates!

Answer 2

Answer:

mass=1000kg

velocity=18km/h=18 x 18/5= 64.8

by the formula of momentum,

momentum(p) = mass x velocity

= 1000 x 64.8

= 64800.0kgm/s.

hope it is helpful.
