2) When the astronaut tossed the basketball while suspended inside the space station, the ball was thrust forward, but the astronaut stayed in relatively the same place. However, when the
two astronauts repeated the same experiment using their bodies rather than a basketball, both
astronauts were propelled equally in opposite directions. Discuss how Newton's Third law of
Motion explains what happened in both scenarios.

Answer body lying face up ;

The answer is: c. from underground

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)
