Calculate the first and second velocities of the car with
two washers attached to the pulley, using the formulas
V1 = 0.25 m/ty, and
v2 = 0.25 m/(t2- t1)
where ty 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.
