A human cannon ball is launched at 25.0 m/s at an angle of 30.0 degrees from horizontal. If the muzzle of the cannon is 6.00 m high and the net is 2.00 m high
A) How far and how high is the human after 0.540 seconds?
B) What is the velocity of the human after 0.540 seconds in terms of i and j?
C) How far down field must the net be for the human to land precisely at a height of 2.00m?
