Question

5. Pumpkin Toss In Denver, children bring their old jack-o- lanterns to the top of a tower and compete for accuracy in hit- ting a target on the ground (Figure 4–15). Suppose that the tower is 9.0 m high and that the bull’s-eye is a horizontal distance of 3.5 m from the launch point. If the pumpkin is thrown horizon- tally, what is the launch speed needed to hit the bull’s-eye?

6. If, in the previous problem, a jack-o-lantern is given an ini- tial horizontal speed of 3.3 m/s, what are the direction and magnitude of its velocity (a) 0.75 s later, and (b) just before it lands?
