Compute all parts of given problem:
Problem: A crankshaft with a diameter of 3.0 cm, rotating at 2800rpm comes to a halt in 1.50s.
Part A: What is the tangential acceleration of a point on the surface of the crankshaft?
Part B: How many revolutions does the crankshaft make as it stops?
I need help to determine the tangential acceleration of a point on the surface of the crankshaft.
