A driver traveling north slows down from 39.1 m/s to 0 m/s in 5.1 seconds. What is the magnitude of the driver's acceleration?

(Note: The standard units for acceleration are "meters per second squared" or "meters per second per second," written as m/s² or m/s/s.)

Answer :

Answer:

7.667 m/s²

Explanation:

The acceleration can be calculated as

[tex]a=\frac{v_f-v_i}{t}[/tex]

Where vf is the final velocity, vi is the initial velocity and t is the time. Replacing vf = 0 m/s, vi = 39.1 m/s, and t = 5.1 s, we get:

[tex]a=\frac{0\text{ m/s - 39.1 m/s}}{5.1\text{ s}}=-7.667\text{ m/s}^2[/tex]

Therefore, the magnitude of the acceleration is 7.667 m/s²
