For this problem, imagine that we have a skier on this really steep slope
0:00:03.000,0:00:07.000
that's 90 meters tall and he comes to this ramp of height 10 meters
0:00:07.000,0:00:09.000
that makes an angle α with the ground.

I want you to tell me using your knowledge of energy and two dimensional motion
0:00:15.000,0:00:20.000
how far away from the ramp will the skier land--what's this distance d?
0:00:20.000,0:00:25.000
Measured from where the skier lands to the bottom of the of ramp when he took off.
0:00:25.000,0:00:32.000
Put your answer here and use 30 degrees for α and use 10 m/s² for g
0:00:32.000,0:00:35.000
rather than 9.8 just so we're all in the same page.

Now, you may end up having to use the quadratic equation in this problem.
