Question

an object of mass 5 kg is moving with a velocity of 10 m/s a force is applied so that in 15sec. it attains a velocity of 25 m/, s what is the force applied on the object

Answer 1

we have initial velocity = 10 and final velocity 25 so by v = u +at we get the acceleration and by f = ma we get the force.

Answer 2

by using v=u +at find a
now put a in foemula
F=Ma
to find force
