A 140 g arrow is shot vertically from a bow whose effective spring constant is 500 N/m. If the bow is drawn 60 cm before shooting the arrow,to what height does the arrow rise?

  • physics - ,

    M g H = (1/2) k X^2
    X = 0.60 m
    M = 0.140 kg
    k = 500 N/m
    g = 9.8 m/s^2
    Solve for H, in meters.

    H = [kX^2/(2Mg)]
