Answer:
45 J
Explanation:
Work done = force × displacement
(<em>displacement</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>shortest</em><em> </em><em>distance</em><em> </em><em>the</em><em> </em><em>object</em><em> </em><em>travels</em><em> </em><em>when</em><em> </em><em>a</em><em> </em><em>force</em><em> </em><em>is</em><em> </em><em>applied</em><em> </em><em>on</em><em> </em><em>it</em><em>)</em>
W = 15 × 3
= 45 J
[Note: While using the formulae, all quantities must be in their SI units.]
