Asked by Jennifer

A 1.2 kg cannon ball is shot off a platform (1) at 10 m/s. It hits a platform (2) and begins to roll without bouncing. The coefficient of friction between platform (2) and the ball is .3. How far does the ball land from platform (2)? How long does it take to hit the ground?

You need a figure to show what is going on. It should show the difference in platform heights and how far apart they are. You have already stated that the cannonball "hits" platform 2. How far below is the ground?
