The amusement park cabin shown in the figure moves rotationally around point O. The change speed of the radius r is constant that equals to r= 0.1*a m / s. The radius r= 4m and angular velocity is ė= 0.1 rad /s when t = 0 s. Assuming there is no force affecting the cabin, calculate the angular velocity of the cabin at t = b sec.
