D L/2 G L/2 B MO A uniform slender rod of mass M=10 kg and length L=3m, is hinged at A. The rod is held in a horizontal position against А the spring (k= 200kN/m) at G, the spring being in compression. When the rod is released from this horizontal position k Rigid (the spring is not connected to the rod), support it will rotate about the frictionless hinge Spring A in a vertical plane. Determine: support a. The minimum...

A ball of mass m= 1.50 kg hangs on a string of length L_0 = 50.0 cm, winch is attached to a vertical shaft at rest, as shown in Fig.-2a. The shaft then starts to rotate at a rate of omega = 150 rpm, as shown in Fig.-2b. Find the angle, theta, that the rotating string makes with the vertical. How much work was done on the system to get it to rotate this fast? The string is now replaced...

Q20 (15 points): A bullet of mass m X102 kg is moving with a speed of 100 m/s when it collides with a rod of mass mR 5 kg and length L m (shown in the figure). The rod is initially at rest, in a vertical position, and pivots about an axis going through its center of mass. The bullet imbeds itself in the rod at a distance L/4 from the pivot point. As a result, the bullet-rod system starts...
