Answer:

4.6 m/s²

Explanation:

The acceleration of an object given it's velocity and time taken can be found by using the formula

[tex]a = \frac{v - u}{t} \\ [/tex]

where

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

Since the body is from rest u = 0

From the question we have

[tex]a = \frac{23 - 0}{5} = \frac{23}{5} \\ [/tex]

We have the final answer as

4.6 m/s²

Hope this helps you
