What is the momentum of a 1,700 kg car travelling in a straight line at 13 m/s?
Anna71 [15]

Answer:

Explanation:

We know that momentum is the product of mass and velocity so here

mass (m) = 1700 kg

velocity (v) = 13 m/s

So now

momentum = m * v

                   = 1700 * 13

                   = 22100 kg m/s

hope it helps :)
