1. Note: Drawings are not to scale.) You are given two objects, each with the same mass. One object is a solid, uniform disk of outer radius R The other object is a thin, uniform rod of unknown length Initially these objects are suspended as shown (each from a frictionless pin located on its uppermost edge). When allowed to oscillate freely as pendulums (through small angular displacements), they have equal frequencies. disk rod Then the rod is removed from its...
could someone help me understand these problems, the proper steps to solve them please. 1) A person walks first at a constant speed of 1.35 m/s along a straight line from point to point and then back along the line from B to at a constant speed of 0.75 m/s. It takes the person 100s to walk from point @to point . a) What is her average speed over the entire trip? (10 points) b) What is her average velocity...
