A 75.0-kg firefighter slides down a pole while a constant friction force of 300 N retards her

Question:

A 75.0-kg firefighter slides down a pole while a constant friction force of 300 N retards her motion. A horizontal 20.0-kg platform is supported by a spring at the bottom of the pole to cushion the fall. The firefighter starts from rest 4.00 m above the platform, and the spring constant is 4 000 N/m. Find
(a) The firefighter’s speed just before she collides with the platform and
(b) The maximum distance the spring is compressed. (Assume the friction force acts during the entire motion.)
