In an old-fashioned amusement park ride, passengers stand inside a 5.0-m-diameter hollow steel cylinder with their backs against the wall. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing suddenly drops away! If all goes well, the passengers will "stick" to the wall and not slide. Clothing has a static coefficient of friction against steel in the range 0.62 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. A sign next to the entrance says "No children under 30 kg allowed."

Q: What is the minimum angular speed, in rpm, for which the ride is safe?

Cassatt Industries is facing a dilemma. During the COVID 19 "Stay at Home" period, many people developed new hobbies. The demand for paint sets increased dramatically. Due to supply chain interruptions, the cost materials to make those paint sets also increased. Cassatt Industries manufactures only two products, Water-Color Paint Sets and Oil-Based Paint Sets. To generate adequate profit and cover its expenses throughout the value chain, Cassatt prices its paint sets at 400% of manufacturing cost. The company is concerned because of the shortage of some materials. The owner Mary Cassatt CEO questions whether the cost numbers generated by the accounting system are correct. She has just learned about ABC and wants to reanalyze her pricing a cost structure based upon anticipated costs using an ABC system.

Information about the company’s products this year are expected to be as follows:

Water-Color Sets

Total direct material costs: $800,000

Total direct labor cost: $300,000

Production volume: 300,000 Water-Color paint sets

Oil-Based Sets

Total direct material cost: $1,200,000

Total direct labor cost: $600,000

Production volume: 20,000 Oil-Based Paint Sets

Currently, the company applies manufacturing overhead on the basis of direct labor hours. The company incurred $900,000 of manufacturing overhead this year and 20,000 direct labor hours (7,000 direct labor hours making Water-Color sets and 13,000 making Oil-Based sets). The ABC team identified three primary production activities that generate manufacturing overhead costs:

Materials Handling ($100,000); driven by the number of material orders handled

Machine Processing ($600,000); driven by machine hours

Packaging ($200,000); driven by packaging hours

The company’s only two products required the following activity levels during the year:

Requirements:

1. Using the company’s current costing system (volume-based costing) find the total unit cost of producing one Water-Color Paint Set
2. Using the company’s current costing system (volume-based costing) find the total unit cost of producing one Oil Based Paint Set
3. Using Activity-Based Costing find the total unit cost of producing one Water-Color Paint Set
4. Using Activity-Based Costing find the total unit cost of producing one Oil Based Paint Set
