Question

The combined mass of a man and a chair suspended at the midpoint of a rope of negligible mass is 50 kilograms. The rope is connected to a weight of 4360 newtons hanging from a massless frictionless pulley. Find the angle.

Answer 1

I assume this rope started out horizontal attached to a wall with the pulley on an opposite wall.

Tension in rope = 4360

if A is angle of rope up from horizontal then

50*9.81 = 2 (4360) sin A
