What is the angular displacement in degrees of ladybug B during a time interval of 2.0 s? Express your answer in degrees to two significant figures.

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. Definition of radial acceleration Radial acceleration ar for an object moving with tangential velocity vt in a circular path of radius r is given by Ap = v²/ pº V ΑΣΦ ar = 0.96 *** Submit Previous Answers Request Answer X Incorrect; Try Again; 4 attempts remaining Review | Constan ? m/s²

An ultracentrifuge accelerates from rest to 9.91 × 10° rpm in 1.75 min. What is its angular acceleration in radians per second squared? angular acceleration: 978 rad/s? What is the tangential acceleration of a point 9.30 cm from the axis of rotation? tangential acceleration: 90.9 m/s? What is the radial acceleration in meters per second squared and in multiples of g of this point at full revolutions per minute? radial acceleration: 1.002 x10° m/s? radial acceleration in multiples of g:

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.
