Question

1) A rugby player passes the ball 7.00m across the field, where it is caught at the same height as it left his hand. At what angle was the ball thrown if its initial speed was 12.0 m/s:

2)A ball is thrown horizontally from the top of a 60.0 m building and lands 100.0 from the base of the building. Ignore air resistance. Determine the initial component (y axis) of the velocity.

3) Zana was flying a rescue plane (horizontally) when she spots a survivor directly below and releases an emergency kit with a parachute. If the package descends at a constant vertical acceleration of magnitude 4.27m/s² and the initial place horizontal speed was 72.3 m/s, how high was the plane when it released the package hits the water 731 m away from the survivor?
