A gyroscope slows from an initial rate of 34.4 rad/s at an angular acceleration of 0.62 rad/s2. 1) How long does it take to come to rest in seconds and how many revolutions does it make before stopping?

1. The blades of a fan running at low speed turn at 300 rpm. When the fan is switched to high speed, the rotation rate increases uniformly to 430 rpm in 5.30 s. What is the magnitude of the angular acceleration of the blades? rad/s2 f60 ssi f60 0 ssro0

A dentist's drill starts from rest. After 3.40 s of constant angular acceleration it turns at a rate of 2.30 x 10 rev/min. (a) Find the drill's angular acceleration. rad/s2 (b) Determine the angle (in radians) through which the drill rotates during this period. rad

(a) What is the magnitude of the tangential acceleration of a bug on the rim of a 12.5-in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 77.0 rev/min in 3.30 s? m/s² (b) When the disk is at its final speed, what is the magnitude of the tangential velocity of the bug? m/s (c) One second after the bug starts from rest, what is the magnitude of its tangential acceleration? m/s² (d) One second after the bug starts from rest, what is the magnitude of its centripetal acceleration? m/s² (e) One second after the bug starts from rest, what is its total acceleration? (Take the positive direction to be in the direction of motion.) magnitude m/s² direction ° from the radially inward direction
