Question

A car that slows down uniformly from 20m/s to 5m/s has an impulse of 30,000kg.m/s. Determine the mass of the car. *

Answer 1

Answer:

momentum = mass × velocity

mass = momentum / velocity

         = 30,000 kg.m/s / [ 20 m/s - 5 m/s]

         = 30,000 kg.m/s / 15 m/s

         = 2,000 kg

f.o.l.l.o.w me if the answer was helpful
