14. Problem on force - Second law of motion and equations of motion

An object of mass 80 \(kg\) is accelerated uniformly from a velocity of 4

m s^{- 1}

to 9

m s^{- 1}

in 7 \(s\).

Find the initial and final momentum of the object. Also, find the magnitude of the force exerted on the object.

Initial momentum \(=\) \(kg\)

m s^{- 1}

Final momentum \(=\) \(kg\)

m s^{- 1}

Force exerted \(=\) \(N\)
