A cheetah can run at a speed of 110 kilometers per hour. Suppose it took a cheetah 20 s to catch an unfortunate gazelle which began 200 m ahead of the cheetah. Assume they are running with constant speeds and along a straight line.
a) Sketch a graph of position versus time for this violent example and estimate the speed of the gazelle.
b) Use two equations, one for the cheetah and one for the gazelle, to solve for the speed of the gazelle.
