A ball is dropped from a bridge 122.5 m above a river. After the ball has been falling for two seconds, a second ball is thrown straight down after it. What must be its initial velocity so that both hit the water at the same time? (take g = 10 m/s2)
- 49 m/s
- 26.8 m/s
- 19.6 m/s
- 9.8 m/s
Answer
(A) 49 m/s
