1 00:00:00,000 --> 00:00:03,000 For this problem, imagine that we have a skier on this really steep slope 2 00:00:03,000 --> 00:00:07,000 that's 90 meters tall and he comes to this ramp of height 10 meters 3 00:00:07,000 --> 00:00:09,000 that makes an angle α with the ground. 4 00:00:09,000 --> 00:00:15,000 I want you to tell me using your knowledge of energy and two dimensional motion 5 00:00:15,000 --> 00:00:20,000 how far away from the ramp will the skier land--what's this distance d? 6 00:00:20,000 --> 00:00:25,000 Measured from where the skier lands to the bottom of the of ramp when he took off. 7 00:00:25,000 --> 00:00:32,000 Put your answer here and use 30 degrees for α and use 10 m/s² for g 8 00:00:32,000 --> 00:00:35,000 rather than 9.8 just so we're all in the same page. 9 00:00:35,000 --> 00:00:39,000 Now, you may end up having to use the quadratic equation in this problem. 10 00:00:39,000 --> 00:00:42,000 If you're out of practice with this or maybe you never learned it, 11 00:00:42,000 --> 99:59:59,999 check for links in the description for help on how to use the quadratic equation to solve this problem.
