Step 1
Given: Angular speed in revolutions per minute = 950 rpm 1 revolution = 2π radians 1 minute = 60 seconds Angular speed in radians per second = (950 rpm * 2π) / 60 Angular speed in radians per second = 95π / 3 Show more…

The drill bit of a variable-speed electric drill has a constant angular acceleration of 3.97 rad/s2. The initial angular speed of the bit is 8.53 rad/s. After 3.87 s, (a) what angle has the bit turned through and (b) what is the bit's angular speed?
