**physics**

and for the second one, i took the rad/s and multiplied it times .1524m to get m/s and it said i was incorrect again.

**physics**

well, for the first one, I changed the rev/s to rad/s which was 8.275 rad/s and then i divided that by 5s to get the angular acceleration and then mulitiplied it by the radius (.1524m) in order to change it to tangential acceleration but it said my answer was incorrect.
