Question

.If a force of 20N acts on a body of mass 10kg for 5s then time rate of change of momentum will be​

Answer 1

Answer:100 kgm/s

Explanation:f=20N

m=10kg

t=5 sec

a=f/m=20/10=2 m/s^2

v=u+at

=0+2*5

=10 m/s

change in momentum=m(v-u)

                                  =10(10-0)

                                  =100 kgm/s
