The blades of a ceiling fan have a radius of 0.314 m and are rotating about a fixed axis with an angular velocity of +1.89 rad/s. When the switch on the fan is turned to a higher speed, the blades acquire an angular acceleration of +2.53 rad/s2. After 0.334 s have elapsed since the switch was reset, what is (a) the total acceleration (in m/s2) of a point on the tip of a blade and (b) the angle  between the total acceleration  and the centripetal acceleration  (See Figure b)?

What is the radial acceleration of the blade tip expressed as a multiple of the acceleration due to gravity, g? Express your answer as a multiple of g.

You are at a playground with a merry-go-round, which is initially sitting still.  You push on it, causing it to accelerate in the angle at a rate of 1.2 rad/s2.  If you push for 3 seconds How many radians will the merry-go-round have turned through during that time?

The rod O A rotates clockwise with a constant angular velocity of 6 rad/s.

A wheel with a radius of 18.0 cm rolls without slipping along a horizontal floor (see the figure). At time t₁, the dot P painted on the rim of the wheel is at the point of contact between the wheel and the floor. At a later time t2, the wheel has rolled through one-half of a revolution. What are (a) the magnitude and (b) the angle (relative to the floor) of the displacement of P during this interval? (a) Number i 67.0 (b) Number 32.5 Units Units At time m ° (degrees) P At time to

The bus's wheels have a radius 26 cm. The bus starts at rest and accelerates at a constant speed until it reaches an angular speed of 10.4 rev/s. During this period, the bus moved 100 m. How many revolutions does the wheel go through?

The angular speed of a rotating platform changes from ω0 = 3.6 rad/s to ω = 6.4 rad/s at a constant rate as the platform moves through an angle Δθ = 5.5 radians. The platform has a radius of R = 12 cm. Calculate the angular acceleration of the platform α in rad/s2.

An object rotates about a fixed axis, and the angular position of a reference line on the object is given by θ = 0.580e6t, where θ is in radians and t is in seconds. Consider a point on the object that is 7.00 cm from the axis of rotation. At t = 0, what are the magnitudes of the point's (a) tangential component of acceleration and (b) radial component of acceleration?
