1. The problem statement, all variables and given/known data A car with a mass of 1100 kg is being pulled by a tow truck exerts a 500 N force on the car and there is a 300 N friction force acting on the car. If the car starts at rest at time t=0, at what time has the truck moved 100 meters? 2. Relevant equations x=v0t + 1/2 at2 3. The attempt at a solution First off, I attempted to draw a free body diagram. Down is gravity Up is normal force left is friction force right is the force acting on the car and the truck Then I proceeded to fill in the variables for the equation above ^^^^ V0 = 0 a = 0.20 m/s2 t=??? (trying to figure this out) x = 100 I ended up with this result: 31.62 seconds. The teacher said it was 33 seconds. Help would be appreciated.
