Question: Is it possible for the lab equipment to record negative position values on the Position vs Time graph? (Hint: When does position data collection start?)

  1. Is it possible for the lab equipment to record negative position values on the Position vs Time graph? (Hint: When does position data collection start?)
    1. No, negative position values are not possible because the position data is recorded in the positive direction.
    2. No, negative position values are not possible because velocity data is recorded in the positive direction.
    3. Yes, negative position values will occur when the cart is moved backwards up the track and therefore has a negative velocity.
    4. Yes, negative position values will occur when the cart is moved backwards up the track past the point where recording started.Which choice is correct?
