14. You throw a 2 kg. Stone straight up into the air with a velocity of 6m/s. What is the max height of the stone and the total time it takes for it to come back down?

  • Physics -

    hf=hi+vi*t-at^2 /2
    0=0+6t-9.8t^2/2
    t(6-4.9t)=0
    time of flight: 6/4.9seconds
    max height time is one-half of that.
    redo the same equation, knowing time is 1/2 the above t.
