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?

  • How can you use the formula h = vt - 16t^2 to solve a Physics / math word problem?
  • If a ball is thrown on a hard surface and bounces straight up, and the initial velocity of the rebound is 64 ft/s, how many seconds later will the ball hit the ground?
  • How do you solve Physics word problems that use quadratic equations?
  • How do you write a quadratic equation for a Physics word problem?
  • How do you solve the equation 0 = 64t - 16t^2?
  • How do you know when you can eliminate an answer that does not make sense in a word problem?
This problem shows the connection between math and Physics. The equation h = vt - 16t^2 is used to create and solve a quadratic equation for the situation of a bouncing ball. This tutorial is great for showing how to solve a basic Physics problem.
