Question

A tennis ball, from rest, rolls down the slope of the drawing. At the end of the slope, the ball becomes airborne and leaves the ground at an angle of 35 ° relative to the horizontal plane.
a) Think of the ball as a thin-walled spherical shell and figure out how far x the ball will fly. Explain everything you do.
b) Discuss if x would increase, decrease or remain the same if the ball was treated as a solid sphere.
c) Discuss the effect of forces from the air on the path of the ball after it enters. Which equations may be relevant? (Hint: think of the ball spinning).
