A colony of troglodytes has been in a lengthy feud with its neighbors on the adjacent cliff. Colony A finally develops an important military breakthrough: it rolls bombs off its cliff at known rates of speed, thus gaining pinpoint accuracy in its attacks. The acceleration of gravity is 9.8 meters per second squared. If the cliffs are separated by 49.8 meters and a bomb is rolled at 8 meters per second, how far down the opposite cliff will it land?
Part B. The troglodyte war continues and a particular offensive momber of colony B is located 149 meters below the top. At what speed must a bomb be rolled to get him? Answer in units of m/s.
