A tow truck is pulling a car. Initially the force that the truck applies to the car is quite large. However, it decreases linearly to zero and remains at zero. Describe the how the acceleration, the velocity and the position change in time during this process. Ok I have no idea where to start with this one. Any suggestions on where to start? So I'm thinking that it's velocity and acceleration is increasing and it's position is increasing also...then the tow truck starts to decelerate causing velocity to decrease until the tow truck comes to rest...position is increasing the whole time. Actually, if it's at a constant velocity, there's no acceleration, then wouldn't that cause the force to decrease linearly to zero?
