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

Explanation

Here `m=100kg`
`u=5ms^-1`
`v=8 ms^-1, t=6s`
Initial momentum of object `p_1=mu`
`=100 times 5=500 kg ms^-1`
Final momentum of object `p_2=mv`
`=100 times 8=800 kg ms^-1`
Force =`(800-500)//6=50 N`
