A 75kg firefighter slides down a pole while a constant friction force of 300N retards her motion. A horizontal 20kg platform is supported by a spring at the bottom of the pole to cushion the fall. The firefighter starts from rest 4m above the platform, and the spring constant is 4000N/m. Assuming that the friction force acts during the entire motion, find (a) the firefighter's speed just before she collides with the platform, and (b) the maximum distance the spring is compressed

A 1.5-kg box is released from rest on a frictionless surface that is sloped at θ = 35◦ above the horizontal.After sliding 1.0 m down the slope, the box transitions smoothly to a rough, horizontal surface, slides forsome distance, and then comes to a stop. If the coefcient of kinetic friction between the box and thehorizontal surface is 0.12, how far along the horizontal surface does the box travel?
