A worker drops a wrench from the top of a tower 95.1 m tall. What is the velocity when the wrench strikes the ground?

  • Physics -

    h=v²/2g,
    v=sqrt(2gh)=sqrt(2•9.8•95.1) =43.17 m/s

  • Physics -

    since velocity of any falling object is the gravitational pull, it is 9.8 m/s. *the negative or positive of the answer depends on the positive direction.
