Answer (1)
SOLUTION:Step 1: List the given values.[tex]\begin{aligned} & W = \text{15 J} \\ & t = \text{4 s} \end{aligned}[/tex]Step 2: Calculate the power[tex]\begin{aligned} P & = \frac{W}{t} \\ & = \frac{\text{15 J}}{\text{4 s}} \\ & = \boxed{\text{3.75 W}} \end{aligned}[/tex]Hence, Sasha uses 3.75 W of power on the chair.
