A 1.2-m-long massless rod is pivoted at one end and swings around in a circle on a frictionless table. A block with a hole through the center can slide in and out along the rod. Initially, a small piece of wax holds the block 40 cm from the pivot. The block is spun at 50 rpm , then the temperature of the rod is slowly increased. When the wax melts, the block slides out to the end of the rod.

Part A

What is the final angular velocity? Give your answer in rpm.

A thin uniform rod has a length of 0.490 m and is rotating in a circle on a frictionless table. The axis of rotation is perpendicular to the length of the rod at one end and is stationary. The rod has an angular velocity of 0.37 rad/s and a moment of inertia about the axis of 3.50×10−3 kg⋅m2 . A bug initially standing on the rod at the axis of rotation decides to crawl out to the other end of...
