Question

7 multiple choice 2 points the graph below relates velocity to time. the graph would most likely apply to which of the following events? a soccer ball that is at rest is suddenly kicked. a ball is thrown upward and returns to the ground. a person who is running at a constant speed decides to run faster. a car traveling at a constant speed applies its brakes and comes to a stop.

Explanation:

Step1: Analyze the graph

The graph shows a period of constant velocity (horizontal line) followed by a decrease in velocity (downward - sloping line) until velocity reaches zero.

Step2: Evaluate each option

• Option A: A soccer ball at rest being kicked would have an increase in velocity from zero, which does not match the graph.
• Option B: A ball thrown upward has a decrease in velocity (due to gravity) while going up, then an increase in velocity (due to gravity) while coming down. This does not match the graph.
• Option C: A person running at a constant speed then running faster would have an increase in velocity, which does not match the graph.
• Option D: A car traveling at a constant speed (horizontal part of the graph) then applying brakes (decrease in velocity until stop, the downward - sloping part) matches the graph.

Answer:

D. A car traveling at a constant speed applies its brakes and comes to a stop.
