A ball of mass 10 g is moving with a velocity of 50 m/s. On applying a constant force on ball for 2.0s,it acquires a velocity of 70 m/s, Calculate:
(i) The initial momentum of ball
(ii) The final momentum of ball
(ii) The magnitude of force applied.

m=10 g = 0.01kg
u=50m/s
F=?
t=2s
v=70m/s
a=v-u/t
=70-50/2=10m/s2
Initial momentum=mu
=0.01x50=0.5
final momemtum= mv = 0.01x70=0.7
F=ma
=0.01x 10 =1N
u=50m/s

Sorry I took mass as 10kg but it was 10g so make little change there
Or u can multiple all ans by 10¯³
This is ur ans hope it will help you in case of any doubt comment below
