A block is given a brief push to the right then allowed to move on a horizontal surface. The two red vertical lines in the diagram are just "markers" and do not stop the block. KL-D Vo 2 Magnitude of accel is a. As shown in the diagram, just after being pushed: the block's speed is vo it is a distance L away from marker 1, and markers 1 and 2 are separated by a distance D. While moving, the block slows down with constant acceleration of magnitude a. It is observed to move past marker 2. Answer both parts below. Part A What is the speed of the block when it reaches marker 1? Your answer will be in terms of vo, a, L, and/or D. Show your work. Part B How much time does the block spend between the two markers? In addition to vo, a, L, and D, you may use the symbol v in your answer to represent the speed at marker 1. Show your work.
