A cannonball is shot at ground level with an initial speed of 50 m/s at a launch angle of 40 toward a castle wall 220 m away. The height of the wall is 30 m. Assume that effects due to the air are negligible. [Express your answer in 3 significant figures] a) How long will it take for the cannonball to strike the wall? b) At what height above the base of the wall will the cannonball strike? c) What is the maximum height the cannonball will reach in the air before coming down?
