Question

The sledder shown in starts from the top of a frictionless hill and slides down into the valley. Suppose that h1 = 4.2 m and h2 = 5.5 m . Part A What initial speed vi does the sledder need to just make it over the next hill? Express your answer with the appropriate units.

Step 1

This means that the sum of the sledder's kinetic energy and potential energy remains constant throughout the ride. At the top of the first hill, the sledder has potential energy due to its height h1 and kinetic energy due to its initial speed Ui. As the sledder Show more…
