You hang an object with mass m = 0.380 kg from a vertical spring that has negligible mass and force constant k = 60.0 N/m. You pull the mass down to a distance 0.030 m from its equilibrium position and release it. You measure the period of the subsequent motion to be 0.500 s.(a) If you pull the mass down0.010 mfrom its equilibrium position and release it, the new period would be which of the following?less than 0.500 s0.500 s greater than 0.500 sThere is no way to tell.(b) If, instead, you change the spring to one with a force constant of56.0 N/m but keep everything else the same, the new period will be which of the following?less than 0.500 s0.500 s greater than 0.500 sThere is no way to tell.(c) If, instead, you change the hanging object to one with a mass of0.530 kg but keep everything else the same, the new period will be which of the following?less than 0.500 s0.500 s greater than 0.500 sThere is no way to tell.

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
