OC userin Physics·8 Dec 20175.34 - Consider the system shown in Fig. E5.34. Block A weighs 45.0 N, and block B weighs 25.0 N. Once block B is set into down- ward motion, it descends at a constant speed. (a) Calculate the coefficient of kinetic friction between block A and the tabletop. (b) A cat, also of weight 45.0 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration (magnitude and direction)? Figure E5.34
OC userin Accounting·10 Dec 2017EXERCISE 3-14 Computing Predetermined Overhead Rates and Job Costs [LO3-1, L03-2, L03-3, LO3-7] Moody Corporation uses a job-order costing system with a plantwide overhead rate based on machine-hours. At the beginning of the year, the company made the following estimates: Machine-hours required to support estimated production ...... Fixed manufacturing overhead cost .... Variable manufacturing overhead cost per machine-hour ....... 100,000 $650,000 $3.00 Required: 1. Compute the predetermined overhead rate. 2. During the year, Job 400 was started and completed. The following information was available with respect to this job: $450 Direct materials requisitioned ..... Direct labor cost ... Machine-hours used ...... $210 40 Compute the total manufacturing cost assigned to Job 400. During the year, the company worked a total of 146,000 machine-hours on all jobs and incurred actual manufacturing overhead costs of $1,350,000. What is the amount of underap- plied or overapplied overhead for the year? If this amount were closed out entirely to Cost of Goods Sold would the journal entry increase or decrease net operating income?
