Physics

To explore the physics of freefall, a curious student climbs tothe top of the Las Vegas-version of the Leaning Tower of Pisa (tobe built in the style of the Las Vegas-version of the Eiffel Tower,the Statue of Liberty, â€¦) with two identical cannonballs andconducts a series of experiments. Part A) The student drops onecannonball, and exactly 1.0 s later drops the other cannonball fromthe same height. What is the time interval between the firstcannonball striking the ground and the second cannonball strikingthe ground? Part B) The student drops one cannonball, and after ithas fallen exactly 1.0 m drops the other cannonball from the sameinitial height. What is the distance between the cannonballs whenthe first cannonball strikes the ground? Part C) The student throwsone cannonball directly upward at 5.0 m/s and simultaneously throwsthe other cannonball directly downward at 5.0 m/s. (This requiresgreat dexterity, but the student has been practicing this maneuverfor several months.) What is the difference in speed between thecannonballs when each ball strikes the ground?
Answer Choices: Less than 1.0 m 1.0 m Greater than 1.0 m Cannotbe determined
