A book slides across a level, carpeted floor with an initial speed of 3.85 m/s and comes to rest after 3.75 m. Calculate the
coefficient of kinetic friction between the book and the carpet. Assume the only forces acting on the book are friction, weight,
and the normal force.

Tom reached a speed of 29 m/s in the downhill skiing competition. Suppose he left the slope at that speed and then slid freely along a horizontal surface. If the coefficient of kinetic friction between his feet and the ground was 0.27 and his final speed was half of his initial speed, find the distance he traveled?
A book with initial velocity 4.46m/s. if the coefficient of kinetic friction between the book and the horizontal floor is 0.4, how far (in meters) will the book slide before coming to rest?
