A 40,000 lb. rocket is launched from sea level straight up, then falls back to earth. The total flight time was 160 seconds. The rocket reached it's apex in 1 minute and 20 seconds. What altitude did the rocket reach before falling back to earth....in miles?
The assembly operation takes two minutes for an operator to perform in a manufacturing firm, producing 24,000 such assemblies per year. The hourly cost for the assembler is $10.00 per hour. You, as a new engineer have redesigned the assembly fixture so that it allows the operation to be performed in 20 seconds. Furthermore, it is now possible to use less skilled operators costing $7.50 per hour. The new fixture will cost $20,000 to construct. If the new fixture design is approved, how long will it take (days) for the cost of the fixture to be returned in labor savings? Assume the factory will continue to produce 24,000 assemblies per year?
