A student in Physics 211 decides to do an experiment. They travel to a city and climb to the roof of a building that is 3.0 x 102 m tall. Then, at the same instant, they drop one rock while a second rock is thrown downward with an initial speed of 16 m/s. Assume both rocks experience negligible air resistance while falling. How much EARLIER does the thrown rock strike the ground? A) 1.1 s B) 1.5 s C) 1.4 s D) they land exactly at the same time
