A bullet is fired with a speed of 450 m/s through a board 20cm thick. If the bullet is subject to a large deceleration of magnitude 10^6m/s^2, will the bullet be able to emerge from the other side of the board.?

  • physics -

    i think it will not be able. because
    Vf^2=-197500 m/s according to this relation Vf^2=Vi^2+2ax

    while x=0.2m, vi= 450 m/s , a=-10^6 m/s^2

    is it right or not?
