NettetSuppose a car travels 108 km at a speed of 30.0 m/s, and uses 2.0 gal of gasoline. Only 30% of the gasoline goes into useful work by the force that keeps the car moving at constant speed despite friction. (See Table 7.1 for the energy content of gasoline.) (a) What is the magnitude of the force exerted to keep the car moving at constant speed?

LIke you initially said you gotta balance the friction and how hard you push to get that constant speed. If you don't get the balance right, and you continuing pushing forever, your speed will increase/decrease forever!!! Share. Cite. NettetA small boat S, drifting in the sea, is modelled as a particle moving in a straight line at constant speed. When first sighted at 0900,S is at a point with position vector (4i−6j)km relative to a fixed origin O, where i and j are unit vectors due east and due north respectively. At 0945,S is at the point with position vector (7i−7.5j)km.
