1. The problem statement, all variables and given/known data A 3000kg truck uses a chain to drag a 500kg log down a road at a constant speed of 10m/s. The friction between the ground and the log is 1000N. If the chain suddenly breaks, what is the acceleration of the truck? 2. Relevant equations a=F/m 3. The attempt at a solution I was plugging it in and i noticed that there it is not given for the force and i don't how to find the force to do the above equation. I really need help.
