A horizontal force, F, holds the ball steady. Given F = 9.00 N, and theta = 12.00 degrees, calculate the mass of the ball.

I honestly have no idea where to begin. Please help.

I'm assuming the ball is on a slope. If so, you can find the component of the weight parallel to the slope, as it will equal the parallel component of the horizontal force.

Draw a free body diagram to start, and then use the hints in Post #2... Please show some effort on you schoolwork problems....
