Describe any differences. the graphs match my predictions V(m/s) a(m/s) 0.92 mist 7. Describe the shape of the acceleration vs. time graph. What does the shape tell you about the acceleration of the cart? +(s) the shape of the acc, vs time graph is a straight line so the acceleration is constant. 8. When the cart is at the closest point to the sensor, what is the velocity at this instant? Is the acceleration zero at this instant? Explain. A+ += 2.45 45 V. Cart moving up and down a track 2. 9. Make a prediction. Draw position vs. time, velocity vs. time, and acceleration vs. time graphs for a cart moving up a ramp, reaches maximum point, and moves down a ramp with the positive direction being up the ramp. Give a reason for V(m/s) x (m) each prediction. Q(m/s) > t(s) -> +(s)
