|| communications satellites are placed in circular orbits where they stay directly over a fixed point on the equator as the earth rotates. these are called geosynchronous orbits. the altitude of a geosynchronous orbit is 3.58 * 107 m (22,000 miles). a. what is the period of a satellite in a geosynchronous orbit

Golf is for old men who smell

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)

You need to calculate the string in between two masses
