A ball is released from a height $h$. If $t_{1}$ and $t_{2}$ be the time required to complete first half and second half of the distance respectively. Then, choose the correct relation between $t_{1}$ and $t_{2}$.

Discuss the observation of Galileo for the objects falling freely.

A stone thrown down with a speed $u$ takes a time $t_1$ to reach the ground, while another stone thrown upwards from the same point with the same speed takes time $t_2$. The maximum height the second stone reaches from the ground is

A stone thrown upward with a speed $u$ from the top of the tower reaches the ground with a velocity $3u$. The height of the tower is

A body is thrown vertically upwards and takes $5$ seconds to reach maximum height. The distance travelled by the body will be same in
