Asked by Tushare yadav

The angular velocity of an engine increase from 1200 RPM to 3000 RPM in 10 second computer angular acceleration and the number of revolution made during this time.

Answers

Answered by Nonetheless
Change in angular velocity is 3000 rpm - 1200 rpm = 1800 rpm.

This happens over a period of 10 seconds, or 1/6 of a minute.

Angular acceleration
= change in angular velocity/change in time
= 1800/(1/6)
= 10800 rpm^2

Number of rotations made during this time
= 1800 rotations per minute x 1/6 minute
= 300 rotations
