Question
A disk of radius 30 cm is spinning about it axis at 60rmp it deacelerate at a constant rate of 2.0 rad/s^2 until it reaches 20 rpm
A find the initial and final angular speed in radians per sec
B fine the time it takes to deacelerate from the initial to the final angular speed
Find how many reveloution are performed in this itime
Find the final tangential and centipetal accelTions
