- A sleigh is being pulled horizontally by a train of horses at a constant speed of 8.05 m/s. The magnitude of the normal force exerted by the snow-covered ground on the sleigh is 6.37 103 N. a. If the coefficient of kinetic friction between the sleigh and the ground is 0.23, what is the magnitude of the kinetic friction force experienced by the sleigh? b. If the only other horizontal force exerted on the sleigh is due to the horses pulling the sleigh, what must be the magnitude of this force?arrow_forwardWhich statement about kinetic friction and static friction is true? (Some of the options mention a horizontal force that friction opposes. This means that a force is pulling horizontally and friction is acting in the opposite direction.) Your answer: The force of kinetic friction changes if the speed of the object decreases. The force of kinetic friction changes if the horizontal force (or forces) it opposes gets weaker. The force of static friction changes if the speed of the object decreases. The force of static friction changes if O the horizontal force (or forces) it opposes gets weaker.arrow_forwardA box of bananas weighing 40.0 N rests on a horizontal surface.The coefficient of static friction between the box and the surfaceis 0.40, and the coefficient of kinetic friction is 0.20.
