A rock climber and a hiker exert the same force as they make their separate way up the same mountain. They both travel the same vertical distance (height) but take different routes. The hiker reaches the top of the mountain before the rock climber. Who did more work, the rock climber or the hiker? Help please! It's a write out response NOT multiple choice!

Depending on how the continental plates move it can cause a continental scale shift.

The figure is missing but we can answer anyway.the correct answer is "releasing the string". in fact, when the person is holding the bow and the arrow, the kinetic energy of the arrow is still zero (because the arrow is not moving). the moment the arrow is released, it acquires a velocity v, so its kinetic energy will become different from zero: where m is the mass of the arrow and v its velocity.  all the other options, instead, do not increase the kinetic energy of the system: -  pulling farther back on the string : this will just increase the elastic potential energy of the system-  holding the arrow higher: this will increase the gravitational potential energy of the system (which is given by u=mgh, where h is the height above the ground)-  decreasing the mass of the arrow: this will decrease the gravitational potential energy of the system (which is given by u=mgh, where m is the mass)
