1.Sled and rider with a total weight of 200 lb travel down smooth slope defined by equation y=x^2/20. At x=40 ft the sled's speed is 10 ft/s. At x=40 ft determine rate of increase of speed and the normal force which the slope exers on the sled. Neglect size of the sled and rider
2.A company can manufacture parts for a cost of $4.00 per unit plus $4,000 for tooling. A semiautomated system has been developed as an alternative. The costs for the proposed method are $40,000 for equipment and $1.00 per manufacturing cost per unit. What is the break-even number of units per year?
