Question

A driver traveling north slows down from 39.1 m/s to 0 m/s in 5.1 seconds. What is themagnitude of the driver's acceleration? The standard units for acceleration are "meters persecond-squared" or "meters per second per second" and it's written as m/s² or m/s/s.m/s²Answer:

Answer 1

7.667 m/s²

Step-by-step explanation:

The acceleration can be calculated as

`a=(v_f-v_i)/(t)`

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:

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

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