1. The problem statement, all variables and given/known data In the diagram above, the horizontal force, F, holds the ball steady. The value of the force is F = 9.5 N, and theta = 10°. Calculate the mass of the ball. What is the tension in the string? 2. Relevant equations ? 3. The attempt at a solution I drew a free body diagram. The ball had 3 forces acting on it. Fg, F and Ft. how do I find the mass? Then I'll be fine to find the tension.
