Question

An object of mass 100 kg is accelerated from velocity 6 m/s upto 12 m/s in 9 secs.Calculate the initial and final momentum of the body.Also find magnitude of firce.​

Answer 1

Initial Momentum=Inital velocity(mass)

=100*6=600kgm/s

Final Momentum=Final velocity(mass)=12*100=1200kgm/s

Acceleration=(Final velocity-Initial

Velocity)/time taken=(12-6)/9=0.6m/s2

Force=mass*acceleration=100*0.6=60N(app)
