A 4500 kgkg truck is parked on a 7.0∘∘ slope. How big is the friction force on the truck?

A truck with a mass of 750 kg is traveling along a wet road at 30.0 m/s  The driver slams on the brakes and skids to a stop.  If the coefficient of kinetic friction between the tires and the road is 0.50: what frictional force stops the truck? how far does it skid?

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 rock climber on a rock slab. The coefficient of kinetic friction between the climber's rock climbing shoes and the rock is 0.70.  If the climber slide down the rock starting from rest, the amount of time it will take the climber to slide to the edge of the rock slab is?  distance=16.4 m and theta is 68 degrees.

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.

What is the cofficient of static friction between the pavement and the car tires?

A warehouse worker exerts a constant horizontal force of magnitude 86.0 N on a 40.0 kg box that is initially at rest on the horizontal floor of the warehouse. When the box has moved a distance of 1.60 m, its speed is 1.00 m/s. What is the coefficient of kinetic friction between the box and the floor?
