I was just hoping someone could check the work I did on this two part problem? :)(adsbygoogle = window.adsbygoogle || []).push({});

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!
