Greek engineers had the unenviable task of moving large columns from the quarries to the city. one engineer, chersiphron, tried several different techniques to do this. one method was to cut pivot holes into the ends of the stone and then use oxen to pull the column. the 4-ft diameter column weighs 13200 lbs, and the team of oxen generates a constant pull force of 1500 lbs on the center of the cylinder g. knowing that the column starts from rest and rolls without slipping, determine the velocity of its center g after it has moved 5 ft and the minimum static coefficient of friction that will keep it from slipping.

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)

Projectile motion is a form of motion experienced by an object or projectile that is thrown near the earth's surface and moves along a curve path under the action of gravity.
