1. The problem statement, all variables and given/known data A steel ball is dropped from a great height. When its velocity is 20m/s its acceleration is 7.35 m/s^2. What is it's terminal velocity? 2. Relevant equations V - V_o = at F = ma (Air resistance isn't given, so I don't think drag force can be used.) 3. The attempt at a solution 1. I know the final net force must equal 0. 2. The answer is 40 m/s, but I am unsure of how to get this answer. 3. I tried calculating drag force and taking the limit as time approaches infinity, but I must be making an error.
