 Question Rotational Work and Energy ( Physics Help and Math Help - Physics Forums Homework Help Archive )Updated: 2008-05-21 20:42:55 (1)
 Rotational Work and Energy I have no idea how to do this question A tennis ball, starting from rest, rolls down the hill in the drawing. At the end of the hill the ball becomes airborne, leaving at an angle of 35? with respect to the ground. Treat the ball as a thin-walled spherical shell, and determine the range x.

 Rotational Work and Energy First off, do you know the Moment Of Inertia equation for a thin walled sphere? If not you'll need it. I'd use the conservation of energy equation to find the velocity at the bottom and then a simple range equation to find the distance. Range would be failrly straightforward here because ho=hf once the ball becomes airborn. That's how I would approach it. Good luck. faust9
