The father drags his child, riding in a sled, up a snowslope. The child and the sled altogether encompass a mass of 59.0kg. The slope makes an angle of 21.0o with the horizontal, and the rope is at a 10.0o angle to the slope. The coefficient of friction among the slope and the sled is 0.23. Determine how much work must the father do to drag the sled 0.2 km all along the slope?
If he does this five times in an hour, Determine his average power output?
