The total time taken by a stone thrown vertically upwards to return to the ground can be calculated using the basic equations of motion. The time taken to reach the highest point is:
t = u / g
where
u = initial velocity = 98 m/sec
g = acceleration due to gravity = 9.8 m/sec²
t = 98 / 9.8 = 10 sec
Since the time taken to ascend and descend is the same, the total time to return to the ground is:
Total time = 2 × 10 sec = 20 sec
