- The man slides the 180-lb crate across the floor by pulling with a constant force of 30 lb. If the crate was initially at rest, how far will the crate move before its speed is 4.0 ft/s? The coefficient of kinetic friction between the crate and the floor is 0.15.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 756 N person travels in his vehicle through a deep circular-shaped dip in the road. When the vehicle passes through the lowest point of the 50.0 m dip, the seat exerts an 1110 N force on the person. Determine the speed of the vehicle at this point.
