1. The problem statement, all variables and given/known data Sorry if i sound stupid, i just can't understand this problem. Bob wants to tow a car with his truck. He loosely attaches a rope between the vehicles. Bob accelerates rapidly with his truck, forcing the rope to snap. Explain the scenario using Newton's First Law. 3. The attempt at a solution I want to say that the car wants to stay at rest, but shouldn't bob's truck be considered an external force acting upon it? Any help would be appreciated.
