compare the s value obtained in (a) to the s value determined using the principle of work and energy.

The 3500 lb automobile shown in Figure 3 is travelling down the 10C inclined road at a speed of 20 ft/s. a) If the driver wishes to stop his car, by using the equation of motion method, determine how far S his tires skid on the road if he jams on the brakes, causing his wheels to lock. The coefficient of kinetic friction between the wheels and the road is pe=0.5. b) Compare the value obtained in (a) to the S value determined using the principle of work and energy 20 ft/s 10 Figure 3.
