A 16.0-kg block rests on a level floor; the coefficient of kinetic friction between the block and the floor is 0.463. A force of 200 N acts for 4.00 m.
How fast is the block moving after being pushed 4.00 m? Assume it starts from rest. (Express your answer to three significant figures.)

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 5.00 kg block rests on a level table. The coefficient of friction between the block and the table is 0.55. A 4.00 kg mass is attached to the block by a string of negligible mass passed over a light frictionless pulley (as shown below). What is the acceleration of the block when the 4.00 kg weight is released?
