1.consider the average speed of a runner who jogs around a track four times. the distance (400m) remains constant for each lap. however, each lap is run 5 seconds slower than the first. the time for each lap increases. the average speed for each lap this is an example of a(n) relationship.
a) increases, direct
b) decreases, direct
c) increases, inverse
d) decreases, inverse

larry and balky set up an experiment to analyze the motion of a marble as it rolled down an incline. they started the marble at the top of the ramp and set up photogates to collect data as the marble rolled down the ramp.

which graph format will allow larry and balky to calculate instantaneous accleration from the slope of the graph?
a) velocity on the y-axis, time on the x-axis
b) distance on the y-axis, time on the x-axis
c) time on the x-axis, distance on the y-axis
d) velocity on the y-axis, distance on the x-axis
