An athlete needs to lose weight and decides to do it by "pumping iron."

(a) How many times must an 85.0 kg weight be lifted a distance of 0.790 m in order to burn off 1.00 lb of fat, assuming that that much fat is equivalent to 3500 kcal?

(b) If the weight is lifted once every 2.00 s, how long does the task take (in hours)?
