Find coefficient of kinetic friction between skis and snow

Reference no: EM1357075

Q. A 65.0 kg skier on level snow coasts 170 m to a stop from a speed of 2.40 m/s. Use the work-energy principle to find the coefficient of kinetic friction between the skis and the snow.

Q. Three equal point charges, each with charge 1.80 mu C, are placed at the vertices of an equilateral triangle whose sides are of length 0.500 m. What is the electric potential energy U of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.)
