A ball rolls on a circular track of radius 0.63 m with a constant angular speed of 1.1 rad/s in the counterclockwise direction. If the angular position of the ball at t = 0 is θ = 0, find the x component of the ball's position at the time 2.5 s. Let θ = 0 correspond to the positive x direction. Find the x component of the ball's position at the time 5.1 s. Find the x component of the ball's position at the time 7.4 s.

An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.200 rev/s. The magnitude of the angular acceleration is 0.881 rev/s². Both the the angular velocity and angular accleration are directed counterclockwise. The electric ceiling fan blades form a circle of diameter 0.800 m. Part E Calculate the magnitude ar of the radial (or centripetal) acceleration of the point at the end of the fan blade. ▾ View Available Hint(s) Hint 1.

A 40.0-cm diameter disk rotates with a constant angular acceleration of 2.60 rad/s2. It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.3° with the positive x-axis at this time. Answer parts a-c.

A 45.0-cm diameter disk rotates with a constant angular acceleration of 2.50 rad/s2. It starts from rest at t = 0, and a line drawn from the center of the disk to a point P on the rim of the disk makes an angle of 57.3° with the positive x-axis at this time. At t = 30 s, find d. the position of P (in degrees, with respect to the positive x-axis).
