I was just hoping someone could check the work I did on this two part problem? :) 18a. A car has a mass of 1200 kg. What's the weight of the car? Answer: 1200 kg*9.8 m/s^2 = 11760 N. b. Disregarding friction, what force must the car motor apply to accelerate the car along a level highway at the rate of 4.0 m/s^2? Answer: 11760 N/4.0 m/s^2 = 2940 kg. Thanks so much in advance!
