1. Consider the graph below. ww (a) Assume the horizontal velocity of a lemur traveling in a straight line along a horizontal surface is given by the graph. The input to the function graphed is time in seconds, and the output is velocity in feet per second. As viewed, the motion is left-right, and the velocity shown is the rightward velocity. Here are some fun links to watch lemurs moving: i. https://www.youtube.com/watch?v=64FP3bDr8_U ii. https://www.youtube.com/watch?v=_14wIQ7MWUo iii. https://www.youtube.com/watch?v=da31-X6Bybk You will note hortizontal and vertical motion of the lemurs; we are only consid- ering horizontal motion. Answer each of the following. Give a sentence that describes what you are looking at in the graph to make your conclusion. i. For all times in (0,17), when is the velocity positive, when is it negative, and when is it zero? ii. For all times in (0,17), when is the acceleration positive, when is it negative, and when is it zero? iii. For all times in (0,17), approximate when the displacement from the initial position is positive, when it is negative, and when it is zero. iv. When is the lemur moving left? v. When is the lemur not moving? vi. When is the lemur's velocity increasing? vii. When is the lemur speeding up?
