Three ice skaters meet at the center of a rink and each stands at rest facing the center, within arm's reach of the other two. on a signal, each skater pushes himself away from the other two across the frictionless ice. after the push, skater a with mass ma = 70.0 kg moves in the negative y-direction at 2.00 m/s and skater b with mass m = 85.0 kg moves in the negative x-direction at 2.50 m/s. find the x- and y-components of the 80.0 kg skater c's velocity (in m/s) after the push. hintvcx= m/svcy=/s

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
