V^2 = 2ax
(7.10 m/s)^2 = 2a(35.4 m)
a = (7.10 m/s)^2 / (2•35.4 m)
= 0.712 m/s^2
<h2><u>The work done by Eva is 120 J</u><u>.</u></h2>
Explanation:
<h2>Given:</h2>
F = 40 N
d = 3 m
<h2>Required:</h2>
Work
<h2>Equation:</h2>
W = Fd
where: W - work, J
F - force, N
d - distance, m
<h2>Solution:</h2>
W = Fd
W = (40 N)(3 m)
W = 120 Nm or 120 J
<h2>Final Answer:</h2><h3>
<u>The work done by Eva is 120 J</u><u>. </u></h3>
