A potter’s wheel is spinning with an angular speed of 4.5 rad/s. When the potter stops working, the wheel slows down with an angular acceleration of -0.5 rad/s 2. Calculate the angle, in radians, through which the wheel has turned by the time its angular speed reaches 1.4 rad/s.

Answer 1

V^2 = Vo^2 + 2a*d.
V = 1.4 rad/s, Vo = 4.5 rad/s, a = -0.5 rad/s^2, d = ?.

Note: d is angular distance in radians.
