An object starts its motion from rest on a circle with a radius of 25 cm. The object reaches the angular velocity of 3000 rad/s in 4 minutes. What is the magnitude of the full acceleration, centripetal and tangential in m/s^2 immediately after t=0?
An object is swung in a horizontal circle. If it starts at position zero (0 rad), has an
acceleration of 2.5 rad/s², and swings for 0.75 seconds, how far around the circle does it
travel? Assume the initial angular velocity to be 0 rad/s.
A disk of radius 2.25 m rotates about its axis. Points on the rim of the disk undergo tangential acceleration of magnitude
1.81 m/s?. At a particular time, the rim has a tangential speed of 1.67 m/s. At a time 0.867 s later, what is the tangential
speed v of a point on the rim, the magnitude of the point's radial acceleration a,, and the magnitude of its total acceleration
