A potter\'s wheel rotates with a constant 1.5 rad/s²angular acceleration. After

Question

A potter's wheel rotates with a constant 1.5 rad/s²angular acceleration. After 5.0s, the wheel has rotated through anangle of 60 rad. a.) What was the initial angular velocity of the wheel at thebeginning of the 5.0s interval? b.) A wheel rotates with a constant velocity of 10rad/s.    1.) Compute the radial acceleration of apoint 0.25m from the axis.    2.) Compute the tangential speed of thepoint 0.25m from the axis.

Explanation / Answer

(a) Angular acceleration () of the potter's wheel = 1.5rad/s2 Angular displacement () = 60 rad Time interval (t) = 5.0 s We know that   = ot +(1/2)t2 Substute all the given values in this formula and solve forthe value of o. (b) Given that           = 10 rad/s           r= 0.25m Radial acceleration is ar = r2 And tangential acceleration is at = r Do all the calculation work And tangential acceleration is at = r Do all the calculation work
