One object has a velocity of -4 feet per second. Another object has a velocity of 3 feet per second. Which object has the greater speed? Explain your answer.



Answer :

To determine which object has the greater speed, we need to focus on the absolute value of their velocities. Speed is essentially the magnitude of velocity without regard to its direction.

1. Identify the velocities:
- The first object has a velocity of -4 feet per second.
- The second object has a velocity of 3 feet per second.

2. Calculate the speeds:
- The speed of the first object is the absolute value of its velocity: [tex]\(|-4| = 4\)[/tex] feet per second.
- The speed of the second object is the absolute value of its velocity: [tex]\(|3| = 3\)[/tex] feet per second.

3. Compare the speeds:
- The first object has a speed of 4 feet per second.
- The second object has a speed of 3 feet per second.

Since 4 feet per second is greater than 3 feet per second, the first object, which has a velocity of -4 feet per second, has the greater speed.
