3. Three masses are connected by thin rigid rods as shown below, and are initially at rest on the top of a horizontal table. A circular blob of clay (velocity shown immediately before the collisi...
A thin rod of mass m and length l rests on a frictionless table and is struck at a point l/4 from its center of mass by a clay ball of mass m moving at speed v. The ball sticks to the rod. If the rod is free to pivot about a frictionless pin at its center, find the angular velocity of the rod after the collision. Also find the velocity of the point at the top of the rod...
Three masses are connected by rigid massless rods, as shown. The 200-g mass (B) is located at the origin (0, 0). (a) Find the x- and y-coordinates of the center of mass. (b) Find the moment of inertia of this system of three connected masses when rotated about the r-axis that passes through mass B? (c) If this system is rotated about the r-axis, from rest to an angular speed of 6 rad/s in time t = 3 s, what...
Problem 14.47) Disks A, B, C, and D can ślide freely on a frictionless horizontal surface. Disks B, C, and D are connected by light rods and are at rest in the position shown when disk B is struck squarely by disk A which is moving to the right with a velocity vo 12 m/s. The masses of the disks are m,-m,-mc - 7.5 kg, and m 15 kg. Knowing that after impact disks A and B are bound togetherV)...
