Chapter 4, Problem 48PCE
A clever inventor has created a device that can launch water balloons with an initial speed of 85.0 m/s. Her goal is to pass a balloon through a small hoop mounted on the observation platform at the top of the Eiffel Tower, 276 m above the ground. If the balloon is to pass through the hoop at the peak of its flight, at what angle above horizontal should she launch the balloon?

in Denver, children bring their old 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 9.0 mm high and that the bull's-eye is a horizontal distance of 3.5 mm from the launch point.
If the pumpkin is thrown horizontally, what is the launch speed needed to hit the bull's-eye?

The vertical wall of the building is h = 7.00 m high, to form a 1-m-high railing around the playground. A ball has fallen to the street below, and a passerby returns it by launching it at an angle of 0 = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. a. Find the speed at which the ball was launched. Answer + b. Find the vertical distance by which the ball clears the wall. Answer c.
