Question

An 80.5 kg tight rope walker falls from a wire positioned above a safety net. If their potential energy exactly halfway down from the top is 2,244 J, what height was the wire positioned above the safety net? Note 1: This question is not direction-specific. Therefore, if using acceleration due to gravity, please use positive 9.81 m/s/s. Note 2: If rounding is required, please express your answer as a number rounded to 2 decimal places.

Answer 1

Given:

Mass of the tight rope walker,

Let be the height of the wire above the safety net

Given that the potential energy of the tight rope walker exactly halfway down from the top is

So
