A 30. kg box comes off a ramp with a speed of 6.0 m/s and slides along a level surface with a coefficient of kinetic friction of 0.30. How far does the box slide before stopping?

A 15 kg box is initially sliding across a frictionless floor with a constant speed of 2.5 m/s.Then, the box encounters a rough surface and travels for 12 meters before coming to astop. What is the coefficient of kinetic friction between the box and rough surface?

A 1500kg car is driving on the road at a speed of 15 m/s. The driver applies the brakes, bringing the car to a stop. If the coefficient of static friction between the car's tires and the road is 0.8, what minimum distance does the car need in order to stop?

A child shoves a 4.6 kg block so that it starts traveling across a level floor with an initial velocity of 3.6 m/s.    If the coefficient of kinetic friction between the block and the floor is 0.29, how far will it travel before coming to rest?

A 80.0 kg skater with the Birmingham Bulls hockey team with an initial speed of 7.8 m/s stops propelling himself and begins to coast across the ice, eventually coming to rest. The coefficient of kinetic friction between the ice and the skate blades is 0.100, and air resistance can be neglected.  How far will the skater travel before coming to rest?

You're standing at the top of a snow-covered hill, sloped at 20.0°. The coefficient of kinetic friction between your sled and the hill is 0.534. Unfortunately, there's a running stream just at the bottom of the hill, and you don't want to get wet. If you and your sled together have a mass of 87.0 kg, with what speed should you push off with to stop just before the stream, 77.0 m down the slope?

A box with with a mass m = 2kg is being pushed up a ramp by an unknown pushing force Fp. The coefficient of static friction between the box and interface is 0.7. The coefficient of kinetic friction between the box and interface is 0.6. The incline of the ramp is 15 degrees. The velocity of the box is constant. The surface of the ramp is 12 m. Fp is removed when the box reaches the top of the ramp. What is the acceleratin of the box after Fp is removed?

In the back of the truck is a 200kg box that has a coefficient of static friction of 0.8 and a coefficient of kinetic friction of 0.4 between the truck and the box. You are driving on the freeway at 25m/s. There is a car ahead of you that is driving at 30m/s. Your front bumper is 30m behind the back of the first car. You would like to pass the other car and pull back into the same lane when your back bumper is 10m ahead of the front bumper of the first car in 5 seconds. The length of the car ahead of you is 3m and the length of your car is 4m.a) What minimum acceleration do you need to do this?b) What distance does your car travel in that time?c) Does the box in your truck start to slide off the truck?

A 1520-N crate is to be held in place on a ramp that rises at 30.0° above the horizontal (see figure). The massless rope attached to the crate makes a 22.0° angle above the surface of the ramp. The coefficients of friction between the crate and the surface of the ramp are uk = 0.450 and us = 0.650. The pulley has no appreciable mass or friction. What is the MAXIMUM weight w that can be used to hold this crate stationary on the ramp? w = ? Crate 22.0 Ramp 30,0

the kinetic friction force that a horizontal surface exerts on a 60 kg object is 50 N. If the initial speed of the object of 25 m/s, what of the distance that it will slide before coming to a stop?
