Would anybody like to join my particle physics/Quantum Mechanics class? I am the teacher and would love for you to join, this class is not just for the "smart" kids. Anybody can learn physics and it's a wonderful subject. To join just go to google classroom and type in 3deqwfn for the class code, I do hope to see you all there! Thank you, answer if you would like more information.

Ithink the answer would be a 

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)
