Select the motion diagram that corresponds to each of the four situations. E.g., if diag. A corresponds to the first situation, diag. C to the second, and none of the diagrams to situations 3 and 4, enter ACNN. Note that the velocity and acceleration vectors are shown; both must be correct!

(i) A ball is thrown horizontally off a high cliff.

(ii) Joe is driving his car at a steady speed, then `puts the pedal to the metal' and accelerates.

(iii) Galileo drops a ball from the Leaning Tower of Pisa. Consider its motion from when it leaves his hand until a moment before it hits the ground.

(iv) A ball rolls down a smooth board tilted at a 15° angle.

IF you copy paste the question in the google, diagrams can be found in the chegg websites. (first website that comes up in the google after the search)

To determine the motion diagrams that correspond to each situation, we need to analyze the given scenarios and match them with the appropriate diagrams. Unfortunately, I am unable to directly access external websites or view specific diagrams from Chegg.

However, I can guide you through the process of identifying the correct motion diagrams for each situation based on the given descriptions and general understanding.

(i) A ball is thrown horizontally off a high cliff:
In this scenario, the ball's initial velocity is purely horizontal, meaning it has zero vertical velocity. As the ball falls due to gravity, only its vertical velocity changes, while the horizontal velocity remains constant.

(ii) Joe is driving his car at a steady speed, then 'puts the pedal to the metal' and accelerates:
When Joe is driving at a steady speed, the car has a constant velocity. However, when he accelerates, the car's velocity changes with time. Acceleration refers to a change in velocity, so the motion diagram for this situation should depict a change in velocity.

(iii) Galileo drops a ball from the Leaning Tower of Pisa:
When Galileo drops the ball, it falls vertically downward under the influence of gravity. The initial velocity is zero, and as it falls, its velocity increases due to acceleration caused by gravity. The motion diagram should show a vertical velocity vector that increases over time.

(iv) A ball rolls down a smooth board tilted at a 15° angle:
When the ball rolls down the inclined board, it experiences an acceleration due to the angle of inclination. The motion diagram for this situation should include a velocity vector with a horizontal component due to the angle of the board.

After understanding the motion principles behind each scenario, try searching for the corresponding motion diagrams by providing specific keywords, such as "horizontal projectile motion diagram," "accelerated motion diagram," or "inclined plane motion diagram." This should help you find relevant diagrams and match them with the given situations.
