1. The problem statement, all variables and given/known data A merry go round with a radius of 3 meters is at rest. The operator starts the merry go round up and it accelerates at a constant rate for 20 seconds. At the end of that time, the merry go round is moving at 10 revolutions per minute. 1) What was the angular acceleration of the merry go round? 2) What is the speed of one of the horses at the edge of the merry go round when the merry go round reaches its maximum rotation rate? 2. Relevant equations let a=angular acceleration let w=angular velocity let r= radius a=rw^2 3. The attempt at a solution So, I solved #1 out, but I'm not sure it's right at all. Here is my work: a=rw^2 =(3)((10*2*(22/7))/60)^2 = 3.31 rad/s^2 And I don't know how to do part 2. Please help.
