If the distance between the photogates in the diagram is 30 cm, and the times for the photogates on the LabQuest are listed as:

Blocked 0.00000

Unblocked 0.00156

Blocked 0.035

Calculate the average acceleration (in fundamental-standard units) of the cart. You should assume and initial velocity of 0 m/s and round your answer to 1 decimal place.

I know the average acceleration equation is delta v over delta t and I know how to find the change in velocity but I'm confused on what times to use.

My attempt:

Velocity=0.30m/(0.035)=8.5714m/s

Acceleration= (8.5714m/s-0m/s)/(0.035s-0s)=244.9m/s^2
