12 m 12 m A 3 m B 3 m Figure 1 Figure 2 A simple trebuchet is constructed as shown above.The projectile mass, ma = M = 1.50 kg, and the counterweight mass, mg = cM, where c is 7.50 x 102. Relative to the masses of the projectile and counterweight, the mass of the rotating arm is assumed negligible and there is no friction in the pivot.There is a mechanism that stops the arm when it becomes vertical, allowing the projectile to be launched horizontally. {If needed, treat both masses as point masses with moment of inertia = (mass)R2.} a.

A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 6.35 g coins stacked over the 11.5 cm mark, the stick is found to balance at the 43.4 cm mark. What is the mass of the meter stick?
A tightrope walker is walking between two buildings holding a pole with length ?=15.5 m, and mass ??=19.5 kg. The daredevil grips the pole with each hand a distance ?=0.575 m from the center of the pole. A bird of mass ??=525 g lands on the very end of the left‑hand side of the pole. Assuming the daredevil applies upward forces with the left and right hands in a direction perpendicular to the pole, what magnitude of force ?left and ?right must the left and right hand exert to counteract the torque of the bird?
