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.

    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.
