Question

A tennis ball, starting from rest at a height h = 2.10 m, rolls down the hill. At the end of the hill the ball becomes airborne, leaving at an angle of 27.0° with respect to the ground. Treat the ball as a thin-walled spherical shell (I = ⅔mr²), and determine the range x.

It's not 3.3972, or 9.78, or 1.7 and I can not figure out the answer.
