A crankshaft with a diameter of 3.0 cm , rotating at 2300 rpm comes to a halt in 1.30 s . What is the tangential acceleration of a point on the surface of the crankshaft?
Homework Equations
W=v/r
Wf=Wi+@t
@=At/r
The Attempt at a Solution
-2300 rpm=138000r/s=13006.19m/s
-v=13006.19m/s
-r=.015m
-t=1.3
-W=867079
-@=666983
-@10004.7
the answer is completely wrong.
