In november 2003, the now-most-distant-known object in the solar system was discovered by observation with a telescope on mt. palomar. this object, known as sedna, is approximately 1700km in diameter, takes about 1.05×104 years to orbit our sun, and reaches a maximum speed of 4.64km/s . calculations of its complete path, based upon several measurements of its position, indicate that its orbit is highly elliptical, varying from 76.0au to 942au in its distance from the sun, where au is the "astronomical unit," which is the average distance of the earth from the sun 1.50×108km . part a what is sedna's minimum speed? part b at what points in its orbit do its maximum and minimum speeds occur? part c what is the ratio of sedna's maximum kinetic energy to its minimum kinetic energy?

1. the materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. she knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. she also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four (4) days.2. at what point should resin be reordered? a. 0 kilograms remainingb. 50 kilograms remainingc. 200 kilograms remainingd. 400 kilograms remaininge. 500 kilograms remaining3. if order size was 1,000 kilograms of resin, what would be the length of an order cycle? a. 0.05 daysb. 4 daysc. 16 daysd. 20 dayse. 50 days4. if the order size was 1,000 kilograms of resin, what would be the average inventory level? a. 50 kilogramsb. 200 kilogramsc. 500 kilogramsd. 800 kilogramse. 1,000 kilograms5. if the order size was 1,000 kilograms of resin, what would be the daily total inventory costs, excluding the cost of the resin? a. $5b. $10c. $20d. $25e. $40
