A bodybuilder loads a bar with 550 Newtons (~125 pounds) of weight and pushes the bar over her head 10 times. Each time she lifts the weight 0.5 meters. How much work did she do?

sheesh

work = force * distance

To calculate the work done by the bodybuilder, we need to know two things: the force applied and the distance over which the force acted.

In this case, the force applied by the bodybuilder is equal to the weight on the bar, which is 550 Newtons. The distance over which this force was applied is 0.5 meters for each repetition of lifting the weight over her head.

To find the work done, we can use the formula:

Work = Force x Distance

Substituting the given values, we have:

Work = 550 N x 0.5 m

Now we can calculate the answer:

Work = 275 Joules

Therefore, the bodybuilder did 275 Joules of work by lifting the weight over her head 10 times.
