Question

why is the time of ascent and time of descent is equal when a ball bounces back from the ground
​

Answer 1

Answer:

Time of descent be t1 seconds and the object final velocity be v m/s. The distance covered will be the same as when the object is thrown upwards.

From equation (1) and (2) we can see that u = v.

t1 = t. time of ascent = time of descent.
