Children bring their jack-o-lanterns to the top of a tower and compete for accuracy in hitting a target on the ground. Suppose that the tower is 10.0 m high and the bull’s-eye is located
4.0 m from the launch point. If the pumpkin is thrown horizontally,
(a) (3 points) What initial launch speed is needed to hit the bull’s-eye?
(b) (3 points) How long will the pumpkin take to hit the bull’s eye?
(c) (3 1/4 points) What is the final velocity of the pumpkin as it strikes the bull’s eye?
(d) (3 1/ 4 points) At what angle does it strike the bull’s eye?
