1. An object of mass, m, is dropped from a height, h, on the surface of the earth.... A. What time, t, will it take to land? B. How fast will it be traveling when it impacts the ground? I know, I know we’ve done this before using the equations of constant linear acceleration... but this time I want you to use the concept of conservation of energy to find the answer. c. Now compare and contrast 2 ways to arrive at the same conclusion. (Yeah, don’t you think the 2 methods may be different but they should come to the same conclusion??!!)
