Question

A person walking starts 0 m/s and after 6 seconds is traveling at

5 m/s. What is the acceleration of the walker?

Answer 1

`a = 0.83 {ms}^( - 2)`

Explanation:

The walking has an initial velocity of 0m/s.

After 6 seconds he is now traveling at 5m/s.

So we use the equation:

`v = u + at`

where u=0 m/s is the initial velocity, v=5m/s is the final velocity, and t=6 seconds is the time.

We substitute to get:

`5 = 0 + 6a`

`6a = 5`

`a = (5)/(6)`

`a = 0.83 {ms}^( - 2)`
