A rigid bar in the shape of a T has a mass of 10 kg. The T-shaped body of mass m is composed of two identical slender bars welded together. End A is constrained to move in the slotted frictionless groove guided by the light frictionless roller as shown in Figure 3. The lower end of the T is released from rest in the vertical plane in the position shown, and the dimension /= 1 m. (i) Determine the location...

A seesaw has an irregularly distributed mass of 40 kg k g , a length of 3.0 m m , and a fulcrum beneath its midpoint. It is balanced when a 60-kg k g person sits on one end and a 80-kg k g person sits on the other end. 1. Express your answer with the appropriate units. Enter negative value if the center of mass is located closer to the 60-kgkg person and positive value if the center of...
