1. The problem statement, all variables and given/known data A tugboat of mass m pulls a ship of mass M, accelerating it. Assume that water friction on the two vessels' is negligible. If the force acting on the tug's propellar is F, what is the tension, T, in the cable connecting the two ships (Variables: F, M, m) 2. Relevant equations F=ma 3. The attempt at a solution to get T I thought I would use the equation, a= (T-mg)/m & a= -(T-Mg)/M However, I cannot figure out how to derive a forumla for T that only involves F, M, and m. I can derive: T= (2gMm)/(M+m) I'm stuck can anyone help?
