Question

A stone is thrown vertically upward. It hits the ground after time T. Find the average speed of the stone.
Options:
1) $\frac{gT}{4}$
2) $\frac{g}{T}$
3) $\frac{gT}{2}$
4) $\frac{g}{2T}$

Answer 1

Answer:

option (1)

Explanation:

average speed is (total distance)/(total time)

total distance will be two times the maximum height reached by particle and total time will be the time required to hit the ground.
