a 710 n daredevil was shot out of a cannon at an upward angle. he landed 2.3 s later in a net at the same height but 35m away from the cannon.

A)what was the magnitude of his initial velocity?
B)what was the launch angle?
C)it took the cannon 0.6 seconds to launch him and the kinetic friction in the cannon was 405 n. what constant force did the cannon apply to the daredevil? (hint after the second attempt.)
