15. Equations of motion

An object of mass 150 \(kg\) is accelerated uniformly from a velocity of 4$m{s}^{-1}$ to 9$m{s}^{-1}$ in 7 \(s\).

 

Calculate the initial and final momentum of the object. Also, find the magnitude of the force exerted on the object. [Enter the values up to two decimal places]
