p11.png Determine the acceleration of the crate if coefficient of kinetic friction between the surface and the crate is 0.35, the mass of the crate is 25 kg, and the angle of the incline is 300.

p1.png Two objects are pulled across a frictionless surface as shown.  Determine the acceleration of the objects for m1 = 6.00 kg, m2 = 4.00 kg and F = 8.00 N.

At what angle would a circular track of radius 75 m need to be banked, so that a car traveling at 25 m/s around the track would not need friction to keep from sliding off?

What maximum speed can a car travel around a circular track of radius 150 m banked at 400 and not slide off, if the coefficient of static friction between the tires and the track is 0.7?

For the next seven questions, assume a safety stock level of 40 and an order quantity of 800, along with the cost, annual demand, average demand, and average lead time information listed previously (which is repeated below): Annual demand = 5000                                                 Holding cost = $4 / unit / year Working days per year = 200 days                               Order cost = $50 Average daily demand = 25 units                                 Average lead time = 6 days The time between orders for this item would be (to the nearest integer)

Assume a safety stock level of 40 and an order quantity of 800, along with the cost, annual demand, average demand, and average lead time information listed previously (which is repeated below): Annual demand = 5000                                                 Holding cost = $4 / unit / year Working days per year = 200 days                               Order cost = $50 Average daily demand = 25 units                                 Average lead time = 6 days The number of orders each year would be (to the closest integer)

Assume a safety stock level of 40 and an order quantity of 800, along with the cost, annual demand, average demand, and average lead time information listed previously (which is repeated below): Annual demand = 5000                                                 Holding cost = $4 / unit / year Working days per year = 200 days                               Order cost = $50 Average daily demand = 25 units                                 Average lead time = 6 days Assume that the standard deviation of demand during the lead time was equal to 40 and you wanted a service level of 84.13%. To the nearest integer (round up if the decimal is .5), how many units per year would be short (unavailable when needed)?  (Take calculations to as many as 6 decimal places.)
