Example
A force of 10N is applied on a box that has a mass of 3 kg. The box acquires an acceleration of 2 m/s2. What is the net force on the box and how much of that is due to friction.Ans: FN = 6N, f=-4N

Example – Uniform motion
1. A 5.8 g bullet leaves the muzzle of a rifle with a speed of 334 m/s. What force (assumed constant) is expected on the bullet while it is traveling down the 0.77 m long barrel of the rifle?
