Back Speed for 400 • Draw a graph for the following scenario: From home, Nicole begins to drive to the store at constant speed. She stops at the stop sign and remembers that she has to go to the bank that is 40 meters past her house. Once she gets to the bank, she doesn’t have her ATM card and has to return home. (Note: All speeds are constant) Back Speed for 500 • Write a brief story • Speed is constant - explaining in the then the speed is graph. constant but faster – stops – turns around fast constant speed – slower constant speed Back Velocity for 100 • It takes Sara 90min to • Step 1 get to Tucson from – D = 180 kilometers Phoenix (180km).

When lines velocity-time graph intersect on a v-t intersect, does this mean that the two cars graph, it means that are passing by each the two cars have other? If not, what does the same velocity. it mean? When lines intersect on a p-t graph, it means that the two cars are passing each other.
