Diving Word Problem

Question

Problem: Lauren dove into a swimming pool from a 15-foot-high diving board with an initial upward velocity of 8 feet per second. Find the time t in seconds it took Lauren to enter the water. Use the model for vertical motion given by the equation h=-16t^2+vt+s, where h is height in feet, t is time in seconds, v is the initial upward velocity in feet per second, and s is the initial height in feet. (hint: let h=0 represent the surface of the pool.)

Answer 1

Substitute values

0 = -16t² + 8t + 15

Can you solve for t and answer?
