Calculate the first and second velocities of the car with
four washers attached to the pulley, using the formulas
v4 = 0.25 m/th, and v2 = 0.25 m/(t2-ty)
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.
what is the first velocity of the car with four washers at
the 0.25 meter mark?
m/s
what is the second velocity of the car with four
washers at the 0.50 meter mark?
m/s

answer:

Our freedom of choice in a competitive society rests on the fact that, if one person refuses to satisfy our wishes, we can turn to another.
