If the coefficient of static friction between the grass and sled is 0.9, determine if the sled moves or not. Explain. If the sled moves determine the acceleration of the sled. (coefficient of kinetic friction = 0.6) 2.) A physics student (90 kg) on skis is pulled horizontally across the dry snow with a rope. If there is friction according to the value below (waxed wood on dry snow), determine the force necessary to accelerate the student at 2 m/s?. 3.)
