Discuss how the following factors could influence the value of velocity you get in Part A: poor timing accuracy by the photogates, poor release of cart giving it an initial velocity (up or down the track), and error in your measurement of the photogate separation distance. Write out your answer in a clear and well supported paragraph. erase this and type in your answer 2) In this experiment, you calculated the average speed of the cart using the time between two photogates. Is it possible to calculate the speed of the cart using only one photogate
