A bus contains a 1500 kg flywheel (a disk that has a 0.55 m radius) and has a total mass of 11000 kg.
m = 1500 kg
r = 0.55 m
mt = 11000 kg
v1 = 19 m/s
v2 = 2.75 m/s
A. Calculate the angular velocity the flywheel must have to contain enough energy to take the bus from rest to a speed of 19 m/s in rad/s, assuming 90.0% of the rotational kinetic energy can be transformed into translational energy.
B. How high a hill can the bus climb with this stored energy and still have a speed of 2.75 m/s at the top of the hill in m?

IM.82 A distributor of industrial equipment purchases specialized compressors for use in air conditioners. The regular price is $55, however, the manufacturer of this compressor offers quantity discounts per the following discount schedule: Option Plan Quantity Discount A 1 - 499 0% B 500 - 1,199 0.75% C 1,200+ 1.50% The distributor pays $68 each time it places an order with the manufacturer. Holding costs are negligible (none) but they do earn 7% annual interest on all cash balances (meaning there will be a financial opportunity cost when they put cash into inventory). Annual demand is expected to be 7,000 units. When there is no quantity discount (Option Plan A, the first row of the schedule listed above), what is the adjusted order quantity? (Display your answer to the nearest whole number.) Number Based on your answer to the previous question, and based on the annual demand as stated above, what will be the annual ordering costs? (Display your answer to the nearest whole number.) Number Using the adjusted order quantity as determined above (two questions back), what will be the average number of units held in inventory? (Display your answer to the nearest whole number.) Number Using the adjusted order quantity as determined above (three questions back), and assuming a materials cost for the given discount, what will be the annual holding cost? (Display your answer to the nearest whole number.)

In the Daytona 500 auto race, a Ford Thunderbird and a Mercedes Benz are moving side by side down a straight-away at 74.5 m/s. The driver of the Thunderbird realizes he must make a pit stop, and he smoothly slows to a stop over a distance of 250 m. He spends 5.00 s in the pit and then accelerates out, reaching his previous speed of 74.5 m/s after a distance of 330 m. At this point, how far has the Thunderbird fallen behind the Mercedes Benz, which has continued at a constant speed?
