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?

Tim got a huge birthday gift from his grandmother. A 400. N crate has been delivered to his driveway. In order to get it started moving toward his door, he has to push it with a horizontal force of 250 N, but as soon as it is moving, he can keep it moving at a constant speed by pushing with a 120 N force. What are the coefficients of static and kinetic friction of Tim's birthday gift and the driveway?
Sammy is doing a strength testing session on the turf in preparation for the upcoming basketball season. Sammy's mass is 55 kg and she is trying to push a 105 kg sled across the artificial turf outside on Raymond Field. The coefficient of static friction between the sled and the turf is 0.3. If Sammy pushes only horizontally against the sled, how much force must she push with to just initiate movement of the sled?
