Question

A body of mass 5 kg undergoes a change in speed from 30 to 40m/s. Calculate its increase in momentum?

Answer 1

initial momentum = 5×30=150
final momentum=5×40=200 so. increase in momentum =200-150=50kgm/s

Answer 2

BONJOUR,
❤ ❤ ❤

initial momentum= 5×30 = 150kg/m/sec.
final momentum= 5×40= 200kg/m/sec.

change in momentum = 200-150= 50 kg /m/sec
