1. The problem statement, all variables and given/known data Okay i was absent for 2 days and missed how to do this stuff. And i got a test tommorow. So its not HW i just got to figure out how to do these problems. So i would really appreciate it if someone just did them and explained how. Cause i don't have much time to figure this out myself. #1 In a circus performance, a monkey is strapped to a sled and both are given an initial speed of 4.00 m/s up a 20.0º incline track. The combined mass of the monkey and sled is 20.0 kg, and the coefficient of kinetic friction between the sled and incline is .200. How far up the incline do the monkey and sled move? #2 A skier starts from rest at the top of a hill that is inclined at 10.5º with the horizontal. The hillside is 200.0 m long, and the coefficient of friction between snow and skis is .0750. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How far does the skier move along the horizontal portion of the snow before coming to rest? 2. Relevant equations (sigma)work = 1/2mf^2 - 1/2mvi^2 3. The attempt at a solution I really don't know how to do these so please help me. Thank you so much to anyone that helps.
