How will you find the height of a tall tower using a long-enough thread? You only have a stop-watch with you. So you can only measure time and not length. Explain the method by stating the formula you will use to calculate the height of the tower.

    h= 1/2 g t^2

    drop the spool of thread.

  • physics -

    you would google it
