    potential energy possessed by a body is on account of its position or configuration. So,

    PE = mass*acceleration due to gravity*height = 20*32.2*6 (avg value of g = 9.81 m/s^2 = 32.2 ft/s^2)

    PE=3864 lb-ft^2/sec^2

    20 lb = 9.07 kg

    6 ft = 1.83 meters

    PE = mgh = (9.07)(9.8)(1.83) Joules
