Question

A stone is thrown vertically from the ground it reaches the maximum height of 500 in 10 seconds after time it be reach the ground maximum height

Answer 1

Explanation:

The time taken to fall from a height of 500m can be calculated using the relation, s = u t + ½ a t²; In this equation s= -500 m ( - sign as ground is downwards from the highest point), u= 0 m/s; a= -10 m/s², t =? -500 = 0× t -½ ×10 t²; ==> t² = 100 s² or t = ± 10 s.
