please help...A wheel 1.0m in diameter is rotating about a fixed axis with an initial angular velocity of 2rev.s1.the angular acceleration is 3rev.s1.
(1)compute the angular velocity after 6s.
(2)through what angle has the wheel turned in this time interval?
(3)what is the tangenial velocity of a point on the rim of the wheel at t=6s?

The units of angular velocity have to be rad/s and the units of angular acceleration have to be rad/s^2.
For (1), you can convert rev/s to rad/s, but your units of angular acceleration are entirely wrong. Time has to be to the 2 power.
Review the problem statement and make sure you got it right. 
im sorry that was a typing error for acceleration...i have converted rev/s to rad/s in question 1..i am not getting the correct answers ,im not sure if it is the equations i am using ,could you please help me figure these questions out..thank you
really appreciate your help
