Question

-. A game show contestant won a prize by pushing a bowling ball 20 meters using her nose. The amount of workdone was 1470 Joules. How much force did the game show contestant exert on the ball?

Answer 1

`\begin{gathered} W=1470J \\ d=20\text{ m} \\ F=\text{?} \\ W=Fd \\ \text{Solving F} \\ F=(W)/(d)=(1470J)/(20m)=73.5\text{ N} \\ \text{The person exerted 73.5N on the ball} \end{gathered}`
