(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?

**drwls**, Monday, January 2, 2012 at 4:39amThe 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.

really appreciate your help
