Figure 2.31 shows how the velocity of four cars changed as they travelled along a straight road. Give reasone for your answers to these questions:
A, which car was travelling at steady speed?
B, which car was decelerating?
C, which car had the greatest acceleration?
(A) Which car was trabelling at steady speed
none
1 B
2, D
3, A
A. The car that was traveling at a steady speed is none other than the one labeled "Sleepy Snail." You see, "Sleepy Snail" was neither in a hurry nor too slow, maintaining a consistent velocity throughout. It's as if the snail decided to take a leisurely stroll on that straight road, leaving behind all the worries of the fast-paced automotive world.
B. Ah, the car that was decelerating... well, that honor goes to "Speedy Turtle." Poor thing was zipping along initially, but then it started to lose its momentum and gradually slow down. Maybe it got tired of being outrun by "Sleepy Snail" and decided to take a breather. We all need a break sometimes, don't we?
C. Now, the car with the greatest acceleration was undoubtedly "Crazy Cheetah." This feline-inspired speed machine didn't waste any time and shot off like a rocket. Its velocity changed rapidly, going from zero to whoosh! It must have had some serious places to be or a pressing appointment with a hairstylist – those spots on a cheetah's fur can be quite tricky to maintain, you know.
Remember, these answers are based on the information provided and a dash of clown humor. Enjoy the ride!
To determine the answers to the questions, we will analyze Figure 2.31, which displays the change in velocity of four cars traveling along a straight road. Let's examine each question individually:
A) Which car was traveling at a steady speed?
To identify the car traveling at a steady speed, we need to look for a car with a constant velocity, indicating that its speed remains constant over time. Look for a car with a horizontal line on the graph, as this demonstrates a constant velocity.
B) Which car was decelerating?
To determine which car was decelerating, we need to identify a car that exhibited a decrease in velocity over time. Look for a downward slope on the graph—specifically, a line that is decreasing over a certain duration. This indicates that the car is slowing down or decelerating.
C) Which car had the greatest acceleration?
To identify the car with the greatest acceleration, we should look for the steepest slope or the line with the most noticeable incline on the graph. Acceleration refers to a change in velocity over time, so the car with the biggest change in velocity will have the greatest acceleration.
By carefully observing the graphical representation of the velocity changes of the four cars in Figure 2.31, you can determine which car was traveling at a steady speed, which one was decelerating, and which car had the greatest acceleration.
