The man at A wishes to throw two darts at the target at B so that they arrive at the same time.
Distance between man and target is 5 m.

a) If each dart is thrown with a speed of 11.3 m/s , determine the angle θC at which the first dart should be thrown. Note that the first dart must be thrown at θC(>θD), then the second dart is thrown at θD.

b) Determine the angle θD at which the second dart should be thrown.

c) Determine the time between each throw.
