The 1440-kg car has a velocity of 26 km/h up the 7-percent grade when the driver applies more power for 10 s to bring the car up to a speed of 64 km/h. Calculate the time average F of the total force tangent to the road exerted on the tires during the 10 s. Treat the car as a particle and neglect air resistance. 100 Answer: F = i kN
