Question

a snowboarder moves down a slope for which theta= 22 degrees. the coefficient of kinetic friction between the board and the snow is 0.21 and her velocity is a constant 8.3 m/s. what will her speed 100 meters past the end of the slope? how far will she slide before coming to a stop?

Answer 1

Subtract the work done against friction from the potential energy decrease. That will tell you the kinetic energy at any point. She will stop when that energy is zero. You can solve for distance X at that point.
