A steel ball is tethered to the end of a cable. The ball is attached to a spinning axle that causes the ball and cable to rotate in a vertical circle counter-clockwise. The ball moves in a circle of radius R=.50 m centered at a height of 5 m above a flat surface. The rate of rotation increases very slowly until the cable snaps. the cable snaps when ac=20 m/s2. (x=0 at center of circle) a) how long does it take for the ball to hit the ground after the cable snaps? b) Relative to the position of the axle over the floor, what is the horizontal displacement of the ball( magnitude and direction)? c) What is the magnitude and direction of the velocity with which the ball hits the ground?

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.
