Question

A body of mass 1 kg moves with an initial velocity of 15m/sec. If its velocity changes to 25m/sec in 5 seconds, find the force acting on the body.

Answer 1

Answer:

mass,m = 1 kg

initial velocity,u = 15 m/s

final velocity,v = 25 m/s

force = m*a

v = u+at

(v-u)/t = a

10/t = a

force,F = 1*10/t = 10/t N
