Lesson Summary:

In this lesson, the formula H = Vt - 16t^2 is used to solve a word problem involving a ball being thrown on a hard surface and bouncing straight up. The initial velocity of the rebound is provided, and using the formula, the time it takes for the ball to hit the ground is found to be 4 seconds. This is a great example of applying physics concepts to real-life scenarios.

Lesson Description:

This is a Word Problem you solve by writing an equation and factoring.
Word Problem 6 - Physics ball falling application-Use the formula given to do this problem. A ball is thrown on a hard surface and bounces straight up. The initial velocity of the rebound is 64 feet per second. How many seconds later will the ball hit the ground?
