[QUOTE="hoxbug, post: 4539854, member: 491217"] [h2]Homework Statement [/h2] A wheel rotating about a fixed axis with a constant angular acceleration of 2.0 rad/s[SUP]2[/SUP] turns through 2.165 revolutions during a 2.0 s time interval. What is the angular velocity at the end of this time interval? [h2]Homework Equations[/h2] I was using the kinematic Equations [itex]\theta[/itex][SUB]f[/SUB] = [itex]\theta[/itex][SUB]i[/SUB] + [itex]\omega[/itex][SUB]i[/SUB]t + 0.5[itex]\alpha[/itex]t[SUP]2[/SUP] Am i doing something wrong? The answers that I can choose are, 9.7 rad/s, 9.1 rad/s, 9.3 rad/s, 9.5 rad/s, 8.8 rad/s All the answers I get are way larger I must be doing something obviously wrong but I just can't see it.
