Ok for the second part I used the equation \theta=\varpit + 1/2\alphat^2
So far that I got .5*30.12*(.73)^2= 8.03 radians
8.03/2\pi = 1.3 revs??
For the third part I have r=12m and 180 rpm which equals (180*2pi)/60= 18.85rads/sec then 18.85/.73= 25.82 rad/sec^2
That gives me omega so...
1. A cars wheels starts from rest and accelerate to 210 rpm in .73 seconds.
a.) Find angular acceleration in radians/sec^2
b.) Find the revolutions completed in the time interval
c.) Find the total acceleration when it is 12m from the rotational axis at 180 rpm.
3. 1. a.) 210x2pi= radians/ min...
