Askier slides horizontally along the snow for a distance of 12 m before coming to rest. the coefficient of kinetic friction between the skier and the snow is μk = 0.060. initially, how fast was the skier going?

We can use work-energy to solve this question. The work done by friction on the skier will be equal in magnitude to the skier's initial kinetic energy. KE = Work (1/2)mv^2 = mg ÎĽk d v^2 = 2g ÎĽk d v = sqrt{ 2g ÎĽk d } v = sqrt{ (2) (9.80 m/s^2) (0.060) (12 m) } v = 3.76 m/s Initially the skier was moving at a speed of 3.76 m/s

Texture and composition are different because they are not the same aspect. texture has to do with feel and so on, where as composition is the chemical makeup which you cant touch like you can texture.
