A tennis ball, starting from rest, rolls down a hill from a height h. At the end of the hill the ball becomes airborne, leaving at an angle of 37 degrees with respect to the ground. Treat the ball as a thin walled spherical shell.
(i) What is the velocity of projection?
(ii) What is the maximum height reached by the ball above the ground?
(iii) What is the range of the ball?

​A shell projected from a level ground has a range R,if it did not explode.At the highest point, the shell explodes into two fragment moving horizontally immediately after the explosio​n.If the lighter fragment falls at a distance r from the point of projection,behind the point of projection,the distance at whichh the other fragments falls from the point of projection is???/
