please show me how to solve symbolically while solving the problem

4 . Starting from rest, a basketball rolls from the top to the bottom of a hill, reaching a translational speed of 7.5 m/s. Ignore frictional losses. (a) What is the height of the hill? (b) Released from rest at the same height, a can of frozen juice rolls to the bottom of the same hillWhat is the translational speed of the frozen juice can when it reaches the bottom? 5. A bowling ball encounters a 0.760-m vertical rise on the way back to the ball rack, as the drawing illustratesignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 7.38 m/s at the bottom of the rise. Find the translational speed at the top. 0.760 m 6. A tennis ball, starting from rest, rolls down the hill in the figure. 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. 1.8 m 35
