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...
