Question

You start at rest, and after running 2 seconds, you reach a speed of 6 m/s. How fast were you accelerating?

a)Vf=6m/s
b) Vi=0m/s
c) t=2s
d) a=Vf−Vi

Answer 1

Given the initial velocity of 0 m/s and final velocity of 6 m/s over a time of 2 seconds, you were accelerating at a rate of 3 meters per second squared (3 m/s²).

Step-by-step explanation:

To calculate how fast you were accelerating given the following conditions:

• Final velocity (Vf) = 6 m/s
• Initial velocity (Vi) = 0 m/s (since you start at rest)
• Time (t) = 2 s
• Acceleration (a) = Vf - Vi, divided by t

Using the formula a = (Vf - Vi) / t, we can calculate the acceleration:

a = (6 m/s - 0 m/s) / 2 s = 6 m/s / 2 s = 3 m/s².

Therefore, you were accelerating at a rate of 3 meters per second squared (3 m/s²).
