3 25 Points A Massless Horizontal Rod Of Length 2s Is Free To Rotate About A Vertical Axle As Shown There Are Two 1 (177.88 KiB) Viewed 20 times
= 3. (25 points) A massless, horizontal rod of length 2S is free to rotate about a vertical axle as shown. There are two small objects on the rod. Object 1 has mass mi and is fixed at the end of the rod. Object 2 has mass m2 and is at rest next to the axle. The axle is given an angular velocity wo. At a time defined to be t 0, object 2 begins to move along the rod so that its distance from the axle is given by ct where c is a known constant. a.What will be the angular velocity of the rod as a function of time? b. What will be the angular velocity of the rod at the instant when object 2 reaches the end of the rod? c. If object 2 leaves the rod when it reaches the end, with a velocity of magnitude of parallel to the rod, what will be the angular velocity of the rod after the object leaves?
