Mech Acceleration in one dimension TW-16 6. Carts A and B move along a horizontal track. The strobe diagram shows the locations of the carts at instants 1-5, separated by equal time intervals. a. At instant 3: • is cart A speeding up, slowing down, or moving with constant speed? Explain. Cart A Cart B • is cart B speeding up, slowing down, or moving with constant speed? Explain. b. Is the speed of cart B greater than, less than or equal to the speed of cart A: • at instant 2? Explain. • at instant 3? Explain. c. During a small time interval from just before instant 2 until just after instant 2, does the distance between cart A and cart B increase, decrease, or remain the same? Explain. Consider the following response to the above question: "For the small interval containing instant 2, cart B is ahead and speeding up, so the distance between the carts must b st be increasing." Do you agree or disagree? Explain. d. Is there any time interval during which cart A and cart B have the same average velocity? If so, identify the interval(s) and explain. If not, explain why not. Is there any instant at which cart A and cart B have the same instantaneous velocity? If so, identify the instant(s) (e.g., "at instant 1." or "at an instant between 2 and 3") and explain. If not, explain why not.
