Little Orphan Annie and her dog Sandy are in trouble on a frictionless snow covered slope in Northern Canada as shown. Annie and the sled have a combined mass of 65.0 kg. A strong massless rope is tied to a stake at S, passes down the slope, around a massless pulley who axle pulls on the sled, back up along the slope to a second massless pulley whose axle is fixed at the edge of the cliff and finally vertically down to Sandy, who has a mass of 45.0 kg and keeps a firm grip on it with his teeth. Calculate the magnitude of the acceleration of the sled along the slope. Answer in terms of gravitational acceleration, g. (Answer: 0.208 g, up the slope)
