A constant Force F is applied by the engine of a stationary car causing it to move to the right. Opposing force F, is a force of magnitude -kv, where k is a constant and v is the velocity of the car. The car has a mass of m. a) Determine the horizontal acceleration in terms of k, v, F and m b)Derive the equation expressing the velocity of the car as a funtion of time t in terms of k, F, and m. I tried using F=ma: F-kv=ma a= (F-kv)/m Then I integrated this from 0 to t and got v=(F-kv)t/m I know that these answers can't be right, since this would be the same result if I had used the equation for constant acceleration. And its not constant acceleration, I'm not sure how to do this. Thanks!
