The flywheel of a steam engine runs with a constant angular speed of 350 rev/min. When steam is shut off, the friction of the bearings stops the wheel in 1.0 h.
A) At the instant the flywheel is turning at 75 rev/min, what is the tangential component of the linear acceleration of a flywheel particle that is 50 cm from the axis of rotation?
B) What is the magnitude of the net linear acceleration of the particle in A?
I calculated the acceleration to be -5.83 rev/s and that it rotates 10500 times before stopping, but I have no idea how to do these two.
