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) Speed for 400 Back
Write a brief story explaining in the graph. Speed is constant - then the speed is constant but faster – stops – turns around fast constant speed – slower constant speed Speed for 500 Back
It takes Sara 90min to get to Tucson from Phoenix (180km). What is her velocity Step 1 D = 180 kilometers T = 90 minutes V = ? Direction - South Step 2 V = d/t + direction Step 3 S = 180m/90min (south) Step 4 2km/min South Velocity for 100 Back
An Amtrak train travels from Phoenix to Flagstaff 240miles in 6 hours. What is the trains average velocity? Velocity for 200 • Step 1 • D = 240 miles • T = 6 hours • V = ? • Direction - North • Step 2 • V = d/t + direction • Step 3 • V = 240mi/6hr North • Step 4 • 40mph North Back
When lines on a velocity-time graph intersect, does this mean that the two cars are passing by each other? If not, what does it mean? No! When lines intersect on a v-t graph, it means that the two cars have the same velocity. When lines intersect on a p-t graph, it means that the two cars are passing each other. Velocity for 300 Back
