An egg is dropped from a height of 90 ft. If acceleration due to gravity is - 16 ft/s2 and initial velocity is Ofts, approximately how

long will it take for the egg to reach the ground?

Step-by-step explanation:

Use the height equation:

y = ½ a t² + v t + h

where y is the height at time t,

a is the acceleration due to gravity,

v is the initial velocity,

and h is the initial height.

Here, a = - 16, v = 0, and h = 90.

y = - 8t² + 90

When the egg lands, y = 0.

0 = - 8t² + 90

8t² = 90

t² = 45/4

t = 3.35

It takes approximately 3.35 seconds for the egg to land.
