A body starts falling freely from height H hits an inclined plane in its path at height h. As a result of this perfectly elastic impact, the direction of the velocity of the body becomes horizontal. The value of H/h for which the body will take the maximum time to reach the ground is .

Answer: 2

Solution

The total time is T = √(2(H − h)/g) + √(2h/g) (the fall to the plane, then a horizontal launch
