Question

an object of mass 5 kg is moving with a velocity of 10m/s.A force is applied so that in 20s,it attains velocity of 25m/s.
what is the force applied on the object?​

Answer 1

Answer:

Apply equation of kinematic : v=u+at

Acceleration, a= v-u/t

= 20-10/20

=0.75ms-²

Force= mass x acceleration

F=5×0.75=3.75N

Hence, force is 3.75N
