Solver the following problem given below:

Problem: The head of a grass string trimmer has 100g of cord wound on a light, cylindrical spool with inside diameter 3cm and outside diameter 18 cm. The cord has a linear density of 10g/m. A single strand of the cord extends 16 cm from the outer edge of the spool.

Part A- When switched on, the trimmer speeds up from 0 to 2500 rev/min in 0.215 seconds. What average power is delivered to the head by the trimmer motor while it is accelerating?

Please, try to give explanation. Thank you.
