Homework Help: Physics mechanics

Posted by Faith on Sunday, November 3, 2013 at 1:14pm.

A piece of cord 2.5m is connected between two points 2m apart horizontally. A massless pulley is placed on the cord and a force 20N at angle - 80 degrees is applied to it.

1. Show that when the pulley reaches a state of rest, the angle that the positions of the cor make with the horizontal differ by 20 degrees.

2. Verify that the relevant equations are satisfied when the smaller angle is 28 degrees and hence determine the tension in the cord.

Thank you
