A block weighing 130. N is on an incline. It is held back by a weight of 45.0 N hanging from a cord that passes over a frictionless pulley and is attached to the block on the incline. Find the angle theta at which the block will slide down the plane at constant speed. coefficient of friction is equal to 0.620(adsbygoogle = window.adsbygoogle || []).push({});

My physics teacher gave me that problem thursday and I still haven't had any luck figuring it out. He said that I would have to use the quadratic formula and a trigonometric identity to figure it out. Any help would be appreciated
