    A 12 kg block begins from rest and slides down an inclined plane. After 10s the block has a velocity of 18 m/s. The plane's angle of Inclination is .524 radians. What is the coefficient of friction between the plane and block? What is the Kenetic energy of the block at t=15s? What is the total work done by all the forces acting on the block after it slides down the plane for a distance of 1m?

    2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses 2.20 gallons of gasoline. Only 30% of the gasoline goes into useful work by the force that keeps the car moving at constant speed despite friction. (The energy content of gasoline is 1.3 ✕ 108 J per gallon.) (a) What is the force exerted to keep the car moving at constant speed? N (b) If the required force is directly proportional to speed, how many...
