A 10 kg box is being pushed across a rough surface with a constant speed of 2 m/s. The person pushing the box slips and stops pushing. The box continues to slide across the surface before coming to rest. If the coefficient of friction between the crate and the surface is 0.1, how far does the box travel before coming to rest?

A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0.The value of d is d = 4.72 m. The block starts at x = 0, and is given a push to the left with an initial speed of 5.37 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down?      -1.47 m     -2.63 m     2.63 m     1.47 m

A truck is traveling at 11.6 m/s down a hill when the brakes on all four wheels lock. The hill makes an angle of 17° with respect to the horizontal. The coefficient of kinetic friction between the tires and the road is 0.876. How far does the truck skid before coming to a stop?

A hockey puck ( mass 160 grams ) slides across the ice. It's initial velocity is 10 m/s. If the coefficient of kinetic friction between the puck and the ice is 0.05, how far will it slide before it stops?
