Question
A 3.0cm diameter crankshaft that is rotating at 2500 rpm comesto a halt in 1.5 s.
a- what is the tangential acceleration of a ponit on thesurface?
b-how many revolutions does the crankshaft make as itstops?
For this question, what are the applicable concepts and/or laws and assumptions and/or simplifications?

a)
α = ω/t
make sure you do the conversions
b) θ = ωo t + ½ α t2
then unconvert from rads to revs
