A book is caused to slide with initial velocity 4.59 m/s on a rough floor. If the coefficient of kinetic friction between the book and the horizontal floor is 0.4, how far (in meters) will the book slide before coming to rest?

Two roofers are installing a new roof. Bob is sitting on the top of the roof that is angled at 23.5 degrees from the horizontal. Nate is sitting 4.1 m further down the roof. In order to get a box of shingles to Nate, Bob just slides the box directly down to him. If the coefficient of kinetic friction for the box and roof is 0.5, then with what speed should Bob initially push the box so that it slides to a stop right as it reaches the Nate?

A 7.5 kg backpack is sliding across the floor.  The coefficient of friction between the backpack and the floor is 0.20.  Answer the following:   Is this static or kinetic friction?

A truck is traveling at 14.7 m/s down a hill when the brakes on all four wheels lock. The hill makes an angle of 19 ° with respect to the horizontal. The coefficient of kinetic friction between the tires and the road is 0.789. How far, in meters, does the truck skid before coming to a stop?

A truck is traveling at 10.0 m/s down a hill when the brakes on all four wheels lock. The hill makes an angle of 11 ° with respect to the horizontal. The coefficient of kinetic friction between the tires and the road is 0.933. How far, in meters,  does the truck skid before coming to a stop?

Antman must supply a force of 8.25x10-3N to a small computer chip to lower it at a constant velocity over a distance of 11.5cm down a slope into a waiting circuit board. If the computer chip has a mass of 5.50g and the slope makes an angle of 23.0° with respect to the horizontal. What is the coefficient of kinetic friction between the computer chip and the slope?

A roller-coaster car is towed up an incline at a steady speed of 0.500 m/s by a chain parallel to the surface of the incline. The slope is 3.00%, which means that the elevation increases by 3.00 m for every 100.0 m of horizontal distance. The mass of the roller-coaster car is 594 kg. Ignoring friction, what is the magnitude of the force exerted on the car by the chain?

A block of mass 1.45 kg is resting on a board with friction.The board is inclined until the mass just starts to slide.  If the angle of the incline when the mass just barely begins to slide is 17.5 degrees,what is the coefficient of static friction between the block and the board?

A block is placed on the midpoint of a ramp that is inclined at an angle of 39.8º from the horizontal, at which point the block immediately starts to slide down the ramp due to the fact that the static friction limit for this particular case is insufficient to hold the block in place. If the coefficient of kinetic friction between the block and the ramp is  0.277 , what is the magnitude of the acceleration of the block as it slides down the ramp.
