Homework Statement
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?
Homework Equations
V - V_o = at
F = ma
(Air resistance isn't given, so I don't think drag force can be used.)
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.
