Answer:
energy dissipated = 132 kJ
Explanation:
mass = 61 kg
height drop = 227 m
velocity = 11 m/s
potential energy due to height drop from top to bottom
             P.E. =  m g h
             P.E. =  61× 9.8× 227
             P.E. = 135,700 J
kinetic energy = [tex]\frac{1}{2}mv^2[/tex]
            = [tex]\frac{1}{2}\times 61 \times 11^2[/tex]
            = 3690.5 J
energy dissipated = P.E - K.E.
               = 135,700 J -3690.5 J
               =132,009.5 J = 132 kJ
