Question
Explain why does a tennis ball bounce higher on hills than in plains?
Solution
The height to which the ball bounces when thrown with velocity u is given by,
The height to which the ball bounces is inversely proportional to the acceleration due to gravity at that place.
Acceleration due to gravity on hills is less than that in plains, therefore the tennis ball bounces higher on hills.
