Jake tosses a coin up in the air and lets it fall on the ground. The equation that models the height (in feet) and time (in seconds) of the parabola is

h(t) = -16t2 + 24 + 6. Approximate the time at which the coin hits the

ground.

Step-by-step explanation:

Given

Required

When will the coin hit the ground

When the coin hits the ground,

The expression becomes

Multiply through by -1

Solve using quadratic formula

Where

Split

or

or

or

But time can't be negative;

So:

Time to hit the ground is 1.71825 seconds
