Q1. Assume the ball's initial velocity was 53^circ above the horizontal and ignoring air resistance, what did the initial speed of the ball need to be to produce such a home run if the ball was hit at a point 0.9 {rm m} (3.0 {rm ft}) above ground level? Suppose that the ground was perfectly flat.

Q2. A 106 m long train begins uniform acceleration from rest. The front of the train has a speed of 23 m/s when it passes a railway worker who is standing 230 m from where the front of train started. What will be the speed of last car as it passes the worker?
