The answer is: 1.8 meters.
Explanation:
An athlete swinging can be considered a pendulum.
The pendulum's maximum height is the point at which it changes direction, which means that its velocity is equal to zero. In this point, for the mechanical energy conservation, all its kinetic energy is transformed into potential energy. Similarly, when the pendulum is at its resting position (when the athlete grabs the rope), its energy is totally kinetic.
Therefore we can say that:
Solving for h:
As we can see, the maximum height is independent on the mass and on the length of the rope, therefore it will be the same for the 100kg-athlete as it is for the 50kg-athlete, since their initial speeds are the same.
We know that the <span>50kg-athlete reached a height of 1.8 m, h</span>ence, the maximum height reached by the 100kg-athlete will be 1.8 m.

Answer:
A. Volume is unchanged
Explanation:
= initial pressure of the gas = 722 torr = 96258.7 pa
= final pressure of the gas = 0.950 atm = 96258.75 pa
= initial temperature = 32 °F = 272.15 K
= final temperature = 273 K
= initial volume
= final volume
Using the Equation
Inserting the values
Hence the volume is unchanged.
