Aball is thrown straight up from the edge of the roof of a building. a second ball is dropped from the roof a time of 1.03 s later. you may ignore air resistance. a-if the initial speed of the first ball is v0 = 8.90 m/s what must the height h of the building be for both balls to reach the ground at the same time?
b-if v0 is greater than some value vmax, a value of h does not exist that allows both balls to hit the ground at the same time. solve for vmax
c-if v0 is less than some value vmin, a value of h does not exist that allows both balls to hit the ground at the same time. solve for vmin.
