An object of mass 100 kg is accelerated uniformly from a velocity
of 5 m s' to 8 m s in 6 s. Calculate the initial and final
momentum of the object. Also, find the magnitude of the force
exerted on the object.

Momentum=mass*velocity
Initial momentum=100*5
=500kg m/s
Final Momentum=100*8
=800 kg m/s
Change in Momentum =300kg m/s
Force = Change in momentum/Change in time
=300/6
=50N

change in momentum is nothing but,
= m(v-u) ÷ t
= 100(8-5)÷6
= 300÷6
= 50 kgm/s
force is nothing but the rate of change in momentum, by newton second law,
= 50N
= m(v-u) ÷ t
= 100(8-5)÷6
= 300÷6
= 50 kgm/s
