Question

step 9: calculate the acceleration for each set of conditions
calculate the first and second velocities of the car with one washer attached to the pulley, using the formulas
v1 = 0.25 m/(t1, avg)
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

Explanation:

Step1: Identify the first - velocity formula

The formula for the first velocity is $v_1 = 0.25\ m/t_{1 - wash}$, where $t_{1 - wash}$ is the average time the car took to reach the 0.25 - meter mark. However, since the value of $t_{1 - wash}$ is not given in the problem, we cannot calculate a numerical value.

Step2: Identify the second - velocity formula

The formula for the second velocity is $v_2=0.25\ m/(t_2 - t_1)$, where $t_1$ is the average time to reach the 0.25 - meter mark and $t_2$ is the average time to reach the 0.50 - meter mark. Without the values of $t_1$ and $t_2$, we cannot calculate a numerical value.

Answer:

Since the values of $t_{1 - wash}$, $t_1$ and $t_2$ are not provided, we cannot calculate the first velocity and the second velocity.
