A mass m = 14 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.12, for a distance d = 5.9 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 38° with the horizontal. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 38° (thus on the incline it is...

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...
