PROBLEM 3 3 Mechanical system consists of solid body 1 of mass mm which is connected by non-elastic cord of negligible mass to the disk 2 of mass m, 4m and radius R. A spring 3 of coefficient of elasticity c is H hinged at the center of the disk. The other spring end is fixed. Disk 2 moves on a horizontal fixed plane without sliding. At the initial moment system is turned out of its equilibrium as body 1 is shifted to xo distance at x direction (according to the figure) and it is released without initial velocity. Assuming the system makes small oscillations around its equilibrium, neglecting all resistances, and if m, R, c, xo are positive constants, find: R C₂ a) kinetic energy of the system; b) total power of the forces acting upon the system; c) differential equation of the system motion (using the body I motion at x direction); d) the law of the system motion (using the body I motion at x direction).

A baseball attachment that helps people with mobility impairments play T-ball and baseball is powered by a spring that is unstretched at position 2. The spring is attached to a cord that is fastened to point B on the 75-mm radius pulley. The pulley is fixed at point O , rotates backwards to the cocked position at 0 , and the rope wraps around the pulley and stretches the spring with a stiffness of k = 2000 N/m. The combined mass moment of inertia of all the rotating components about point O is 0.40 kg·m2. The swing is timed perfectly to strike a 145-gram baseball travelling with a speed of V0 = 10 m/s at a distance of h = 0.7 m away from point O. Knowing that the coefficient of restitution between the bat and ball is 0.59, determine the velocity of the baseball immediately after the impact. Assume that the ball is travelling primarily in the horizontal plane and that its spin is negligible.
A 30kg mass is tied to a uniform rod whose mass and length are 80-kg and 8-m, as shown below.
