A sled and rider have a total mass of 60.0 kg. They are on a snowy hill. The coefficient of kinetic friction between the sled and the snow is 0.150. The angle of the hill's slope measured upward from the horizontal is 24.0°. What is the acceleration of the rider? Is the acceleration greater, less than, or equal to your result if a more massive rider uses the same sled on the same hill? Explain.
