HOW DO I DO THIS?
A daredevil is shot out of a cannon at 45.0° to the horizontal with an initial speed of 28.0 m/s. A net is positioned a horizontal distance of 51.0 m from the cannon. At what height above the cannon should the net be placed in order to catch the daredevil?

Calculate the time to reach the 51m mark:
t = 51/(28 cos(&theta))
Calculate the elevation of the daredevil
S = ut+(1/2)gt²
Solve for S.
Double-check your results or else the poor (dare)devil will land on hard ground.
