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.

What is the first velocity of the car with four washers at the 0.25 meter mark?

0.11
m/s

What is the second velocity of the car with four washers at the 0.50 meter mark?

0.27
m/s
