A small block with a mass of 0.0600 kg is attached to a cord passing through a hole in a frictionless, horizontal surface (Figure 1). The block is originally revolving at a distance of 0.49 m from the hole with a speed of 0.77 m/s . The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 9.0×10−2 m . At this new distance, the speed of the block is 4.19 m/s...

2) 40 pts. Block A, which is attached to a cord, moves along the slot of a horizontal forked rod. At the instant shown, the cord is pulled down through the hole at O with an acceleration of 4 m/sec/sec and its velocity is 2 m/s. Determine the acceleration of the block at this instant. The rod rotates about O with an angular velocity of 4 rad's and an...

A red ball is thrown down with an initial speed of 1.2 m/s from a height of 25 meters above the ground. Then, 0.6 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.8 m/s, from a height of 0.8 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. 1)What is the speed of the...
