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

Answer:

$a = 0.83 {ms}^{ - 2}$

Step-by-step 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:

$5 = 0 + 6a$

$6a = 5$

$a = \frac{5}{6}$

$a = 0.83 {ms}^{ - 2}$
