Post Video requests?

Welcome to Physics In Five! I'll be recording at least 2 new videos every week, and requests are welcome.

Just post a problem/topic, and I'll get right on it!

Our techer gave us this problem and I need some help:

A girl coasts down a hill on a sled, reaching a level surface at the bottom with a speed of 6.8 m/s. The coefficient of kinetic friction between runners and snow is 0.044, and the girl and the sled together weigh 620 N. The acceleration of gravity is 9.8 m/s^2. How far does the sled travel on the level surface before coming to a rest? Answer in units of m.

Thank you,
Peter Drossopoulos
