Ch2_1 #4

Part A:
See the Notes Ch2 Sheet 3". The blue curve is the accelerated case.
Part B: On the Sheet after Sheet 5", if you "hang" the green triangle
from the red curce (constant velocity case) you measure the constant slope. See on Sheet 5 how slope of the x-t-graph and velocity are related. The green triangle "hung" from the blue curve (accelerated case) shows you how to measure the average slope between 2 time points. Apply these slope-measurements to the 4 figures and don't forget to consider the sign (+ or -) of the slope when making your judgement.
