In this lab you will compare the position, velocity, and acceleration versus time graphs for a cart moving with constant velocity and then with constant acceleration using a recording timer. The timer uses a carbon paper disk and an vibrating arm to mark a ticker tape ~60 times a second. Procedure: 1 run for constant velocity and 1 for constant acceleration Data: one table with the data for the graphs listed below - each dot is 1/60 of a second - you will need at least 20 data points fo for position in order to calculate velocity and acceleration. Graphs: 6 total ( p vs. t, v vs. t, a vs t, for both constant velocity and constant acceleration) Calculations: velocity = (Dx)/(Dt) and acceleration = (Dv)/(Dt) Conclusion: Explain your results in terms of the kinematic equations x = xo vot (1/2)at2 and v = vo at
