I need help please! Angular deceleration
A circular saw blade completes 1150 revolutions in 42 s while coasting to a stop after being turned off. Assume constant deceleration.
(a) What is the angular deceleration? (rpm/s)
(b) What is the initial angular speed? (rpm)
w=wo+at
w^2=wo^2+2a(change in theta)
I tried to plug in one equation into the other but it did not work. Any help would be much appreciated.
