Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

1. A motor gives disk A a counter-clockwise angular acceleration whose magnitude is a = 1.5 t (rad/s2) where t is in seconds. (Yes, that means the disk is slowing down.) If the disk has an initial velocity of @= 6 rad/s, what is the velocity and acceleration of the bucket at 1=2 s? w = 6 rad/s A 0.15 m. B

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A simple friction drive consists of two disks A and B. Initially, disk B has a clockwise angular velocity of 550 rpm, and disk A is at rest. It is known that disk B will coast to rest in 65 s. However, rather than waiting until both disks are at rest to bring them together, disk A is given a constant angular acceleration of 3 rad/s² counterclockwise. A 2.5 in. B 3 in. Determine at what time the disks can be brought together if they are not to slip. (You must provide an answer before moving to the next part.) The disks can be brought together at t= S.
The two pulleys shown may be operated with the V belt in any of three positions. If the angular acceleration of shaft A is 6 rad/s2 and if the system is initially at rest, determine the time required for shaft B to reach a speed of 400 rpm with the belt in each of the three positions.
