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...

2. (25 pts.) A simple pendulum of length L = 1.0 m, with a mass mp = 5.0 kg at the end, is held at a 90° angle and released from rest. There are also two blocks, A and B with masses ma = 10 kg and mb = 15 kg, at rest on a horizon- tal, frictionless surface. After the release, the pendulum collides elastically with block A, which in turn collides completely/perfectly inelastically with block B. a. Immediately...

Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane
Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane and connected with a massless unstretchable string running over a massless, frictionless pulley to M2, which is hanging over the ground. The two masses are released initially from rest. The inclined plane has coefficients of static and kinetic friction μs and μk respectively where the angle θ is small enough that mass M1 , would remain at rest due to static friction if...

3. [7] The two blocks shown below have masses m = 1.0 kg and m2 = 3.0 kg. Assume that 0 = 25°, k = 16 N/m, and H=0.11 between mi and the incline. Neglect friction in the pulley and assume that the pulley and string and cable are massless. If this system is released initially at rest with the spring in its equilibrium position (no stretch), what is the speed of m2 after it...

Angular Momentum and Inelastic Collisions Two balls, each with mass M/2, are attached to the ends of a thin rod of length L = 0.45 m and negligible mass. The rod is free to rotate in a horizontal plane without friction about a fixed vertical axis through its center. With the rod initially at rest (as shown), two wads of wet putty hit the balls at the same time and stick to them. Assume that the wads of putty have...
