Arock is thrown vertically upward from ground level at time 0. at time t1 it passes the top of a tall tower, and later, at time t2, it reaches its maximum height. what is the height of the tower? give your answer in terms of the given variables and g.

h = g t₂ t₁ - t₁²

Explanation:

given,

At t = 0 s the rock is at ground level

At t = t₁ rock reaches at the height of the tower

Assuming height of tower be h

At t = t₂ rock is at the highest point.                        

distance of the tower = speed × time

at the highest point velocity is zero

using the kinematic equation

v = u +a t                                            

h = g t₂ t₁ - t₁²
