Allen, Chloe, Jaycee, and Kim are all biking at the same speed. At one point, Chloe speeds up and pedals at a new speed for several minutes. She slows down slightly as she rides up a hill. Finally, she slows way down to allow her friends to catch up with her.

The tables show the mass of each bicyclist, the kinetic energy (KE) of each bicyclist at the original speed, and the kinetic energy of Chloe at four different speeds.

Make a graph of kinetic energy versus mass for the bikers. Label each biker on graph. (4 points) Make a second graph of Chloe's kinetic energy versus her speed. (4 points) Summarize the relationship shown in each graph. (2 points)
