Answer:
Explanation:
<h3>a and b</h3>
We can use the following formula, from kinematics:
where is the final speed, is the initial speed, a is the acceleration and d the distance traveled.
Knowing that the final speed is zero, and the initial speed is
we obtain
Now, knowing that
then
<h3>c</h3>
We can use the following formula
so
<h3>d</h3>
