In a circus, a “human cannonball” is launched from a cannon and lands in a net. The cannon releases him at the same height as the net. His initial velocity is 18.3 m/s in a direction 40.0° above the horizontal. a) For how much time will he be in the air? b) How far does he travel horizontally? c) What is the velocity upon impact?

Question
In a circus, a “human cannonball” is launched from a cannon and lands in a net. The cannon releases him at the same height as the net. His initial velocity is 18.3 m/s in a direction 40.0° above the horizontal.
a) For how much time will he be in the air?
b) How far does he travel horizontally?
c) What is the velocity upon impact?
The circus manager from the previous question wants to make the stunt more dramatic by firing the stuntman through a hoop 9.0 m high then land in a safety net at the same height as the cannon. The cannon’s angle is changed to 45.0° and the velocity is increased to
21.0 m/s. The manager needs to know where to place the hoop and safety net.
a) How far from the cannon should the safety net be placed?
b) What is the time required to reach the height of the hoop?
c) How far from the cannon should the hoop be placed?
