1. A 1900 kg car traveling at a speed of 24 m/sskids to a halt on wet concrete where μk = 0.50.
a. How long are the skid marks in meters.?
2. For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 40mph? Suppose that μs=1.00 and μk=0.80.
3. A 17 kg crate is placed on a horizontal conveyor belt. The materials are such that μs = 0.43 and μk= 0.25.
a. Draw a free body diagram showing all the forces on the crate if the conveyer belt runs to the right at constant speed.

1) It is friction that provides the force for a car to accelerate, so for high-performance cars the factor that limits acceleration isn't the engine; it's the tires. For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 60 mph? Suppose that μs=1.00 and μk=0.80. Express your answer to two significant figures and include the appropriate units. 2) A 22 cm diameter bowling ball has a terminal speed of 69 m/s. Suppose...

For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 50 mph? Suppose that μs=1.00, μk=0.80, and μr=0.02. It's possible for a determined group of people to pull an aircraft. Drag is negligible at low speeds, and the only force impeding motion is the rolling friction of the rubber tires on the concrete runway. In 2000, a team of 60 British police officers set a world record by pulling a Boeing 747,...

1) It is friction that provides the force for a car to accelerate, so for high-performance cars the factor that limits acceleration isn't the engine; it's the tires. Part A For typical rubber-on-concrete friction, what is the shortest time in which a car could accelerate from 0 to 70 mph? Suppose that ?s=1.00, ?k=0.80, and ?r=0.02. 2.) The forces in (Figure 1) are acting on a 1.0 kg object. What is ax, the x-component of the object's acceleration? 3.)A crate...
