Textbook Question
Chapter 4, Problem 67TS
The decrease in PE of a freely falling object equals its gain in KE, in accord with the conservation of energy. (a) Using simple algebra, find an equation for an object’s speed v after falling a vertical distance h. Do this by equating KE to the objects change in PE. (b) Then figure out how much farther a freely falling object must fall to have twice the speed when it hits the ground.
