Given a set-up like that described in the figure below you measure T2 = 8N and 02 = 140° while T3 = 12N and 03 = 295°. Determine what T1 and O1 would have to be in order for the system to be in equilibrium. (ie. The sum of the forces T1, T2, and T3 on the knot needs to be zero :) ORisco CAUTION CAUTION Model ME47 FORCE TABLE

Newton's First Law of Motion

If a very smooth ball is rolled down an inclined surface with zero friction, the ball will continue to roll indefinitely for an infinite time, in an attempt to reach to the same height on the opposite hill!
