A car with a mass of 1000kg is traveling with a velocity of12m/s.The friction due t air resistance is 750N.
a) What is the magnitude of the force needed(bythe engine) to accelerate the car to 18.9m/s in 4.5s?
b) What is the magnitude of the force neededto keep the car at a constant velocity
c) How far will it travel in 4.5(in problema)?
