1. The problem statement, all variables and given/known data 1. If a 0.2 kg ball is dropped from a height of 8 m, what is its kinetic energy when it hits the ground? 2. Jane, looking for Tarzan, is running at top speed (4.6 m/s) and grabs a vine hanging vertically from a tall tree in the jungle. How high can she swing upward? 2. Relevant equations Kinetic Energy = (1/2) mass*gravity*height Potential Energy= mass*gravity*height not sure if this equation is right.... distance=(1/2)(gravity)(time^2) Velocity= (change in distance)/time 3. The attempt at a solution my work got deleted for both the question (error in webassign) and now I have no idea how I got the answers. (both wrong) But they were 9.5J for the first one and 14.2m for the second question.
