Deena made a chart to summarize features of a velocity vs. time graph for objects with constant acceleration and objects with constant velocity. which best describes deena’s error?
the line for constant velocity is not horizontal; it is diagonal and slopes downward.
include the area of the rectangle under the line to find displacement for constant acceleration.
find acceleration by finding the area of the rectangle above the line.
find velocity by calculating the slope of the line.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
