a very strong young child tosses a stone into the air. his father times the stone's travel and finds that it takes the stone 2.8 seconds to return to the child's hand. how high did the stone rise?

  • physics -

    Y=(1/2)*(gravity)*(time)^2
    where time=1.4 sec

    takes 1/2 the time to go up and 1/2 the time to go down

  • physics -

    thank you :)
