Calculate the first and second velocities of the car with one washer 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, rounded to two decimal places, in Table E.

What is the first velocity of the car with one washer at the 0.25 meter mark?

m/s

What is the second velocity of the car with one washer at the 0.50 meter mark?

m/s

To calculate the first velocity of the car with one washer at the 0.25 meter mark, we need to use the formula v1 = 0.25 m / t1.

Let's assume that the average time t1 for the car to reach the 0.25 meter mark is 1 second.

v1 = 0.25 m / 1 s
v1 = 0.25 m/s

Therefore, the first velocity of the car with one washer at the 0.25 meter mark is 0.25 m/s.

To calculate the second velocity of the car with one washer at the 0.50 meter mark, we need to use the formula v2 = 0.25 m / (t2 – t1).

Let's assume that the average time t2 for the car to reach the 0.50 meter mark is 2 seconds.

v2 = 0.25 m / (2 s - 1 s)
v2 = 0.25 m / 1 s
v2 = 0.25 m/s

Therefore, the second velocity of the car with one washer at the 0.50 meter mark is also 0.25 m/s.

In Table E:
First velocity: 0.25 m/s
Second velocity: 0.25 m/s
