To get off a frozen frictionless lake, a 70.0 kg person takes off a 0.150 kg shoe and throws it horizontally directly away from the shore with a speed of 2.00 m/s. If the perrson is 5.00 m from the shore, how long does it take for her to reach it?

  • physics -

    Her momentum after throwing will be equal and opposite to that of the shoe. Use that fact to get her velcoity V towards the shore.

    V*70 kg= 0.150 kg * 2.00 m/s

    Time = (5 meters)/V

  • theoretical degree in theoretical physics -

    yes
