3. Harper the 10kg sheep sees some delicious hay in the feeder all the way across the pasture.
She starts running from a standstill, steadily increasing her speed to 6.0 m/s during the first
four seconds. During the next six seconds, she runs at a constant 6.0 m/s.
A. On the graph provided, draw her velocity versus time during the entire 10-
second interval. Be sure to label the axes (with units) and make your
numerical scale clear.
B. How far did Harper run in those ten seconds? Show your work.
