Problem 5.33 The coefficient of kinetic friction between a 50 kg crate and the warehouse floor is 80 % of the corresponding coefficient of static friction. The crate falls off a forklift that is moving at4 m/s and then slides along the warehouse floor for a distance of 3.5 m before coming to rest. Part A What is the coefficient of static friction between the crate and the floor? Express your answer to one significant figure. #PLEASE SHOW WORK

A spring is mounted horizontally. A crate, which has a mass of 8.5 kg is pressed against the spring with a force of 350N As a result the spring is compressed a distance of 82.0 cm The mass is then released and is allowed to slide along the horizontal surface which has friction. The coefficient of kinetic friction between the crate and the surface is 0.65 How much work will be done on the crate by the frictional force from...

Th figure below shows a mass m=1.0 kg which is initially moving
with speed v=7.2 m/s at the top of a frictionless hill of height
h=4.9 m. It slides down the hill until it encounters a flat section
with unknown coefficient of kinetic friction µk. If the object
travels a distance D=11.1 m before reaching a speed of v/2, what is
the coefficient of kinetic friction µk? (use picture, but first
