Asked by John

Catching a wave, a 77-kg surfer starts with a speed of 1.1 m/s, drops through a height of 1.60 m, and ends with a speed of 8.5 m/s.

How much nonconservative work was done on the surfer?

Answered by dewey

W+(.5*77*1^2)+(77*9.8*1.65)=(.577*8.3^2)+(77*9.8*0)
w=1368.67

based on nonconservative equation neglecting kinetic energy
