I need a little help on this problem. A toboggan and rider have a m of 90kg and travel down along a smooth slope. defined by equation y=0.08x^2. At the instance x=10 m, the toboggan's speed is 5m/s. At this point, determine the rate of increase in speed and the normal force which the toboggan exerts on the slope. Neglect the size of the toboggan and the rider.

Please see a picture of the problem here that I scanned and upload.
Thank you
