Question

An objecte of mass 5kg is moving with a velocity of 10ms^-1. A force is applied so that in 15 s,it attains a velocity of25ms^1.What is the force ​

Answer 1

Explanation:

Apply equation of kinematic

v=u+at

Acceleration, a=

t

v−u

=

20

25−10

=0.75ms

−2

Force= mass x acceleration

F=5×0.75=3.75N

Hence, force is 3.75N
