Checkpoint 4 Worked-out solution available at LarsonAppliedCalculus.com

At time *t* = 0, a diver jumps from a diving board that is 12 feet high with an initial velocity of 16 feet per second. The diver’s position function is *s* = −16*t*^{2} + 16*t* + 12.

**a.** When does the diver hit the water?

**b.** What is the diver’s velocity at impact?

**(a)**

To determine

**To calculate:** The time when the diver hits the water, when at time

Explanation

**Given Information:**

At time

**Formula used:**

Zero product law:

If

Where *a, b* belongs to set of real numbers.

**Calculation:**

The position function of the diver is given by

To find the time when the diver hits the water, substitute

Factor out

It can be further si

**(b)**

To determine

**To calculate:** The velocity at impact when the diver hits the water where the diver's position function is given by
