Question
A sphere of mass 3.3 10-4 kg is suspended from a cord. A steady horizontal breeze pushes the sphere so that the cord makes an angle of 41° with the vertical when at rest
(a) Find the magnitude of that push.
(b) Find the tension in the cord.
(a) Find the magnitude of that push.

Use the triangle.
tan41=horizonal push/mg
Then,
cos41=mg/tension
tan41=horizonal push/mg
Then,
cos41=mg/tension
