You walk 100 m east in 50 s, then turn and walk 100 m west in 50 s. What is true about the values of

Question

your speed and velocity over the entire walk? (1 point)

Your speed was 2 m/s, and your velocity was 0 m/s.

Your speed was 0 m/s, and your velocity was 0 m/s.

Your speed was 2 m/s, and your velocity was 2 m/s east.

Your speed was 4 m/s, and your velocity was 0 m/s.

Answer 1

To analyze the situation:

1. Speed Calculation:

   • Speed is defined as the total distance traveled divided by the total time taken.
   • You walked 100 m east and then 100 m west, totaling 200 m of distance.
   • The total time taken was 50 s + 50 s = 100 s.
   • Therefore, speed = total distance / total time = 200 m / 100 s = 2 m/s.

2. Velocity Calculation:

   • Velocity is defined as the displacement (change in position) divided by the total time taken.
   • You start at a point, walk 100 m east, and then return 100 m west. Your final position is the same as your starting position, resulting in a displacement of 0 m.
   • Total time for the walk is still 100 s.
   • Therefore, velocity = displacement / total time = 0 m / 100 s = 0 m/s.

In summary:

• Your speed was 2 m/s.
• Your velocity was 0 m/s.

The correct statement is: Your speed was 2 m/s, and your velocity was 0 m/s.
