Two cars travel in the same direction along a straight highway, one at a constant speed of 55.0 mi/h and the other at 70.0 mi/h. Assume the cars start at the same point and arrive at the same destination which is 10.0 miles away.
a. Sketch a position vs. time graph. On this graph put both car 1 (55.0 mi/h) and car 2 (70.0 mi/h).
b. Convert units to meters and seconds. Show your work.
c. Determine how long it takes car 1 to travel 10.0 miles.
d. How much sooner does the faster car arrive at the destination 10.0 miles away?
Suppose after 10.0 miles car 2 travels the next 5.50 miles in 6.00 minutes.
e. Sketch the overall position vs. time graph for car 2.
f. Determine the overall average velocity of car 2.
g. Sketch the average velocity line in your graph from part e. Make sure all of your lines are labeled in the graph.
