Calculate the acceleration of the car for each set of conditions using the formula

a = (v2 – v1) / (t2 – t1)

where v2 and v1 are the first and second velocities and t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. Acceleration is reported in m/s2. Record these accelerations, to two decimal places, in Table E.

The acceleration for the car with one washer is

m/s2.

The acceleration for the car with two washers is

m/s2.

The acceleration for the car with three washers is

m/s2.

The acceleration for the car with four washers is

m/s2.

In order to determine the accelerations for each car, we need to know the velocities and average times taken to reach the 0.25 and 0.50 meter marks. Since this information is not provided in the question, we are unable to calculate the accelerations for each car.
