Answer:
Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula
[tex]a = \frac{v}{t} \\ [/tex]
where
a is the acceleration
v is the velocity
t is the time
From the question
v = 12 m/s
t = 4 s
We have
[tex]a = \frac{12}{4} \\ [/tex]
We have the final answer as
Hope this helps you
