Mr. Purley crashed his car with the greatest g force ever survived by a human being. He decelerated from 53.6m/s to
zero in a distance of only about .59m calculate Mr. Purley's
acceleration.

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?

The horizontal blue line through the middle of the lens is called the optical axis. as the lamp is moved above or below the axis, keeping the horizontal distance to the center of the lens constant, how does the horizontal distance from the lens to the image change?

Energy transformations that involve one transformation from one type of energy to another are called transformations.
