The drive propeller of a ship starts from rest and accelerates at 2.55 x 10-3 rad/s² for 2.35 x 103 s. For the next 1.68 x 10³ s the propeller rotates at a constant angular speed. Then it decelerates at 2.77 x 10-3 rad/s2 until it slows (without reversing direction) to an angular speed of 2.23 rad/s. Find the total angular displacement of the propeller. Number i Units

At t = 0, a wheel rotating about a fixed axis at a constant angular deceleration of 0.51 rad/s2 has an angular velocity of 0.8 rad/s and an angular position of 7 rad. What is the angular position of the wheel after 2 s in rad units?

A bar on a hinge starts from rest and rotates with an angular acceleration a = 13 + 7t, where a is in rad/s? and t is in seconds. Determine the angle in radians through which the bar turns in the first 4.53 s. 226 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four- digit accuracy to minimize roundoff error, rad

18 of 25 During the spin cycle of your clothes washer, the tub rotates at a steady angular velocity of 38.3 rad/s. Find the angular displacement A0 of the tub during a spin of 81.7 s, expressed both in radians and in revolutions. rad AO = revolutions AO =

A wheel rotates at a constant rate of 3.20 x 103 rev/min. (a) What is its angular velocity in radians per second? (Enter the magnitude.) rad/s (b) Through what angle does it turn in 37 s? Express the solution in radians and degrees. in radians in degrees rad

A student is sitting on a swivel seat and is holding a (1.20x10^0) kg weight in each hand, rotating at (1.5600x10^0) rad/s when the weights are held in outstretched arms 0.75 m from the axis of rotation. How fast is the student rotating in units of rad/s when pulling the weights in to the axis of rotation? Express you answer with three significant figures.  (The student's body can be approximated as a cylinder with mass of 65 kg and radius of 0.25 m).

A uniform disk of radius 0.491 m and unknown mass is constrained to rotate about a perpendicular axis through its center. A ring with the same mass as the disk is attached around the disk's rim. A tangential force of 0.229 N applied at the rim causes an angular acceleration of 0.115 rad/s². Find the mass of the disk. mass of disk: 3.08 kg
