hf=29.9*sinTheta*time-1/2 g t^2
distance:
49.8=29.9cosTheta*time solve for time, put it in the first equation, and solve for final height, hf
A daredevil is shot out of a cannon at 49.7◦ to the horizontal with an initial speed of 29.9 m/s. A net is positioned at a horizontal dis- tance of 49.8 m from the cannon from which the daredevil is shot.
The acceleration of gravity is 9.81 m/s2 .
At what height above the cannon’s mouth should the net be placed in order to catch the daredevil?
