Question

A = 2 m/s

Find the acceleration of a runner that goes from 2 ft/s to 20 ft/s in a matter
of 3 s.

Answer 1

To calculate the runner's acceleration from 2 ft/s to 20 ft/s over 3 seconds, use the formula a = (Vf - Vi) / t, resulting in an acceleration of 6 ft/s².

Step-by-step explanation:

The subject of this question is Physics, and is likely suitable for a High School level student. To find the acceleration of a runner that goes from 2 ft/s to 20 ft/s in a span of 3 seconds, we use the formula for acceleration which is:

a = (Vf - Vi) / t

Where:

• Vf is the final velocity
• Vi is the initial velocity
• t is the time in seconds over which the change in velocity occurs

Plugging in the given values:

a = (20 ft/s - 2 ft/s) / 3 s = 18 ft/s / 3 s = 6 ft/s²

Therefore, the acceleration of the runner is 6 ft/s².
