Document Summary
The 10 kg block rests on a smooth incline. If the spring is originally stretched 0. 5 m, determine the total work done by all the forces acting on the block when a horizontal force p = 400 n pushes the block up the plane s = 2m. The 3500 lb automobile travels down the inclined road at a speed of 20 ft/s. If the driver jams on the brakes, causing his wheels to lock, determine how far s the tires skid on the road. The coefficient of kinetic friction between the wheels and the road is 0. 5. Crates a and b weigh 100 lb and 50 lb respectively. If they start from rest, determine their speed when t = 5s. Also, find the force exerted by crate a on crate b during the motion. The coefficient of kinetic friction between the crates and the ground is 0. 25.
