1. The problem statement, all variables and given/known data A 3.0-cm diameter crankshaft that is initially rotating at 2500 rpm comes to a halt in 1.5 s. What is the tangential acceleration of a point on the surface of the crankshaft? How many revolutions does the crankshaft make as it comes to a stop? 2. Relevant equations at = Dv/Dt 3. The attempt at a solution honestly I am really stuck on this because the only formula that I can find is this one. Any ideas on where to head with it?
