Standing on a bridge, you throw a 3.0 g stone straight upward with speed of 2.5 m/s. How long does it take to return to the original position?

  • Physics -

    while rising,
    v = v0 + at
    0 = 2.5 - 9.8t
    t = .255

    That's the time to stop rising.
    Total time in the air is thus 0.510 sec
