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?
