Question

The force acting on a body when it's momentum changes by 10 kgm/s in 5 second is -------- N

Answer 1

10/5=5 newton
............................

Answer 2

f=m(v-u)/t By using this formulae we can find force

Change in momentum is given to us = 10kgm/s

F=m/t = 10/5 = 5 N

Hope it helps u
