A dockworker loading crates on a ship finds that a 25-kg crate, initially at rest on a horizontal surface, requires a 72-N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 55 N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor.

A 1.14x10^4 kg lunar landing craft is about to touch down on he surface of the moon, where the acceleration due to gravity is 1.6 m/s^2. At an altitude of 165m the craft's downward velocity is 18.0m/s. To slow down the craft, a retrorocket is firing to provide an upward thrust. Assuming the decent is vertical find the magnitude of the thrust needed to reduce the velocity to zero at the instant when the craft touches the lunar surface.
