The rotating blade of a blender turns with constant angular acceleration 1.50 rad/s2. (a) How much time does it take to reach an angular velocity of 36.0 rad/s, starting from rest? (b) Through how many revolutions does the blade turn in this time interval?

Solution to 11E Step 1 2 Angular acceleration of blade =1.5 rad/s Final angular velocity =36 fad/s Initial angular velocity =0irad/s Step 2 (a) From equation of motion, f + it 2 36 rad/s=1.5rad/s x t t=36/1.5 t=24s
