1. The problem statement, all variables and given/known data A skier leaves a slope with an initial speed of 5 m/s. Her speed at the bottom of the slope is 13 m/s. What is the height of the slope? 2. Relevant equations PE= mgh KE= 1/2mv^2 3. The attempt at a solution PE + KE1 = KE2 PE=KE2-KE1 mgh = 1/2mv^2 -1/2mv^2 gh = 1/2v^2 -1/2v^2 h = 1/2mv^2 -1/2mv^2 / g when I plug everything in, I get 14.9 the answer is 7.3 what am I doing wrong?
