The figure below shows a hovercraft that "floats" on a cushion of air, allowing it to move freely without friction. Initially, the hovercraft is not moving. However, there is a spring-loaded canon on the hovercraft that can launch a canon ball at high velocity in the î direction. When the canon pushes the ball out the back, the ball pushes on the hovercraft and propels it forward. Let m, denote the mass of the canon ball, and let mp represent the mass of the hovercraft without the ball. Just ahead of the hovercraft, suppose there is a hill of height H, and a maximum slope of angle 0 somewhere in the range 10° < 0 < 30°. H Given, mb, mp, H, 0, and g, answer Question 1 below. In communicating your answer, you must follow the guidelines enumerated in the Problem Solving Checklist and the Free Body Diagram Checklist. 1. What is the minimum speed (measured by an observer who is not moving) you should launch the ball so that the hovercraft can travel all the way up the hill?
