a ball is dropped from the top on an 80-m high building. what speed does the ball have in falling 3.5 s?
I keep getting the answer 34.3m/s but it is counted wrong. I found an answer on Chegg that say 29.4 m/s but I can't figure out how they are getting that answer.

  1. v = g t
    = 9.8 * 3.5 = 34.3 m/s
    I agree with you.
