Nuts is dropped from a tree and falls for 8.5 seconds before it hit ground.
1) What was the displacement in meter of nut?
2) With what velocity doe nut hit ground?
3) What is the velocity of nut when it has fallen to 4.25 seconds?
4) What is displacement of nut during the time interval from 2.125 sec. to 6.375 seconds

  • Physics -

    d= 1/2 g t^2
    vf=g*t

    for the last, get the dispacement at the 6.3 sec, then the displacement at 2.2 sec, and subtract them.
