The Cart start at position x=0 mm at time t=0s , if the length of the index card is 5cm, and the distance between the photogates is 290 mm, Time 1.075 State 1=1
Time 1.185 State 1=0
Time ?? State 2=1
Time ?? State 2=0
What is the speed of the cart
What is the position of Gate 1
Write the expression for position vs Time for the cart
