1. A skier slides horizontally along the snow for a distance of 29 m before coming to rest. The coefficient of kinetic friction between the skier and the snow is µk = 0.010. Initially, how fast was the skier going?
2. f kinetic = Coeff. of friction * Normal Force
Work Energy Theorem = (1/2 mass * Final Velocity^2)-(1/2 mass * Initial Velocity^2)
3. In the WET, the masses cancel out, I get an equation of Initial Velocity^2= 2Final Velocity ^2.
Only problem is the final velocity is zero so I get an initial velocity of zero as well, but that's is impossible...
