Question

A Vehicle of mass 300kg travels at a velocity of 90km/h find its momentum

Answer 1

speed v = 90 kmph
= 90*5/18 m/s
= 25 m/s
mass m = 300 kg

therefore, momentum = m * v
= 25 * 300
= 7500 kg m/s

Answer 2

mass=300kg
velocity=90km/h=25m/s

momentum=mass×velocity
=300×25
=7500kg.m/s

hope it helps...
