A colony of troglodytes has been in a lengthy feud with its neighbors on the adjacent cliff. Colony A finally develops an important mili- tary breakthrough: it rolls bombs off its cliff at known rates of speed, thus gaining pinpoint accuracy in its attacks. If the cliffs are separated by 45.5 m and a bomb is rolled at 7 m/s, how far down the opposite cliff will it land? The acceleration due to gravity is 9.8 m/s2 .
Answer in units of m.
The troglodyte war continues, and a particu- larly offensive member of colony B is located 105 m below the top.
At what speed must a bomb be rolled to get him?
Answer in units of m/s.
