2. A daredevil is shot out of a cannon at 40.0degree above the horizontal with an initial speed of 25.0m/s. A net is positioned at a horizontal distance of 50.0m from the cannon. (a) At what height above the cannon should the net be placed in order to catch the daredevil? (b) How long is the daredevil on the air, before reaching the net? (c) What is the maximum height reached by the daredevil? (d) How long does it take for the daredevil to reach the maximum height?
