An initially stationary 2.0kg object accelerates horizontally and uniformly to a speed of 10m/s in 3.0s. In that 3.0s interval, how much work is done on the object by the force accelerating it? What is the instantaneous power due to that force at the end of the interval and at the end of the first half of the interval?
A 2.0kg ball, initially moving to the right at a speed of 3m/s, collides head-on with another ball of mass 3.0kg, initially moving to the left at 4m/s. The collision was elastic. Find the velocities of both balls after the collision.

Object A is moving due east, while object B is moving due north. They collide and stick together in a completely inelastic collision. Momentum is conserved. Object A has a mass of mA = 16.8 kg and an initial velocity of = 7.37 m/s, due east. Object B, however, has a mass of mB = 29.0 kg and an initial velocity of = 5.03 m/s, due north. Find the (a) magnitude and (b) direction of the total momentum of the...
