A student investigаtes the mоtiоn оf а cаrt rolling off a horizontal table. The student collects position and time data while the cart moves along the table, then measures how far the cart travels horizontally after leaving the table. Part A - Measurement and Uncertainty The student measures the height of the table five times using a meter stick. The results are shown below. Trial Table Height (m) 1 0.806 2 0.802 3 0.809 4 0.804 5 0.807 Part B - Motion in One Dimension While the cart moves along the table, the student records its position as a function of time. Time (s) Position (m) 0.0 0.00 0.5 0.80 1.0 1.60 1.5 2.39 2.0 3.20 Part C: Motion in Two Dimensions (Projectile Motion) After leaving the table, the cart lands on the floor a horizontal distance of 0.65 m from the table edge.Assume: The cart leaves the table horizontally Air resistance is negligible g=9.8 m/s2g = 9.8 , text{m/s}^2
Yоur respоnse tо this question will be cаptured by the HonorLock Proctoring Video Recording. There is no need to uploаd а video file for this question. A student opens a small spigot on the side of a water tank so that a thin stream of water shoots horizontally out of the nozzle and falls to the floor, landing some distance away. In your video, address all of the following: 1) Describe the motion in both directions Describe what the water stream is doing horizontally after it leaves the nozzle. Describe what the water stream is doing vertically after it leaves the nozzle. 2) Explain how the horizontal motion and vertical motion differ Explain why the horizontal and vertical motions can be analyzed separately. State whether each direction has constant velocity, constant acceleration, or changing velocity, and explain why in plain language. 3) Time of flight Explain what determines how long a droplet of water stays in the air from the nozzle to the floor. Discuss whether increasing the water’s horizontal exit speed would change the time it is airborne. Explain your reasoning. 4) Comparison scenario At the exact same moment a droplet exits the nozzle horizontally, another droplet is released from rest directly below the nozzle (no sideways motion) from the same height. Which droplet reaches the floor first? Justify your answer using physics ideas (cause-and-effect reasoning), not equations alone. 5) Common misconception Identify one common misconception students have about “faster horizontal motion means it falls faster/slower,” and briefly explain why that idea is incorrect. Expectations Speak clearly and show your reasoning. You may use hand gestures or a quick sketch on paper. Equations may be mentioned, but the conceptual explanation matters most.
