Question

A bird drops of stick to the ground from a height of 95 ft. The function h= 16t^2+95 gives the sticks approximate height h above the ground, in feet, feet r seconds. At above what time does the stick hit the ground

Answer 1

• 2.44 seconds (above 2 seconds)

Explanation:

When the stick hits the ground it has the height of zero.

Substitute h with 0 and solve the given equation for t:

`- 16t^2 + 95 = 0\\16t^2 = 95\\t^2 = 95/16\\t = √(5.93) \\t=2.44`
