Question

Problem 11.64 Constants Driving on asphalt roads entails very little rolling resistance, so most of the energy of the engine goes to overcoming air resistance. But driving slowly in dry sand is another story. Ifa 1600 kg car is driven in sand at 5.8 m/s, the coefficient of rolling friction is 0.06. In this case, nearly all of the energy that the car uses to move goes to overcoming rolling friction, so you can ignore air drag in this problem Y Pa en Ex Provide F O Type here to search
