Answer:
<h2>1.67 m/s²</h2>Explanation:
The car’s acceleration can be found by using the formula
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
From the question we have
We have the final answer as
<h3>1.67 m/s²</h3>Hope this helps you
<span>The runner is moving by uniformly accelerated motion, starting from rest (so, his initial velocity is zero). The law of motion of the runner is
</span>
<span>
where x(t) is the distance covered after time t, and a is the acceleration of the runner. By re-arranging the formula, we get
</span>
<span>
We know the runner has covered a distance of S=12m in t=4.0 s, and if we plug these numbers into the equation, we find the acceleration of the runner:
