2.(a)Annual requirement of an item is 3550 units. Each item cost of the company is 14 RO. The manufacturers offers discount (Concession) of 15 % and ordering cost is 0.450 RO. Inventory carrying cost is 15 %. Find i) EOQ. b) In above problem, if company is offering discount of 12% of the item cost, the storage cost will increase to 18%. Determine i) EOQ ii)Optimum No.orders; ii) time between two consecutive orders.
Rods are mass produced by a machine. The specification required the length of each rod to be between 42.49 cm and 42.51 cm. The machine produces rods whose lengths are normally distributed with standard deviation 0.005 cm. a) b) Determine the percentage of rods produced which would be rejected if the machine is set so that the mean length of the rods is 42.501 cm. c) Determine the mean length the machine must be set so that only 3 rods in 1,000 will be of length less than 42.494 cm. If there is a need to reduce the total percentage of rejects (oversize and undersize) what should be the mean setting of the machine? You are required to show the normal distribution curve to determine the answer for Part (a) and (b).

Please help me with this homework. Thank you in Advance.
A piece of wood weighing 160 lb is pushed from the top of a plane slide which is 50 feet long and inclined 30° to the horizontal. Air resistance (in pounds) is numerically equal to the velocity (in feet per second), the coefficient of friction is 0.5, and the wood starts sliding with initial velocity 8 ft/sec. A) How fast is the wood moving 1.5 seconds after it starts sliding? B) How far has it slid 1.5 seconds after it starts sliding? C) How long will it take for the wood to reach the bottom of the slide?
