Robin exerts a force of 100 N in pulling back his bow by 0.5 m. He fires the arrow (mass=0.2 kg) vertically upwards.
a-How much energy is stored in his bow.
b-How high does the arrow go?

  • physics -

    a) Stored energy = Work
    = Force x (distance string is pulled)

    b) M g H = stored energy
    Solve for the height, H
