To find the force Sarah expends, we can use the formula for work:
Work = Force × Distance
Plugging in the given values, we have:
84 J = Force × 3 m
To solve for Force, we can divide both sides of the equation by 3:
Force = 84 J / 3 m
Simplifying the expression, we get:
Force = 28 N
Therefore, Sarah expends a force of 28 N.
