- A gymnast does cartwheels along the floor and then launches herself into the air and executes several flips in a tuck while she is airborne. If her moment of inertia when executing the cartwheels is 13.5kgm2 and her spin rate is 0.5 rev/s, how many revolutions does she do in the air if her moment of inertia in the tuck is 3.4kgm2 and she has 2.0 s to do the flips in the air?The angular acceleration of a rotating rigid body is given by =(2.0-3.0t)rad/s2 . If the body starts rotating from rest at t=0 , (a) what is the angular velocity? (b) Angular position? (c) What angle does it rotate through in 10 s? (d) Where does the vector perpendicular to the axis of rotation indicating 0 at t=0 lie at t=10s ?Check Your Understanding A centrifuge used in DNA extraction spins at a maximum rate of 7000 rpm, producing a “g-force on the sample that is 6000 times the force of gravity. If the centrifuge takes 10 seconds to come to rest from the maximum spin rate: (a) What Is the angular acceleration of the centrifuge? (b) What is the angular displacement of the centrifuge during this time?
- If a rigid body has a constant angular acceleration, what is the functional form of the angular velocity In terms of the time variable?A flywheel is rotating at an angular velocity of 100 rad/s. A brake is applied to the flywheel and the angular velocity is reduced to 20 rad/s. Find: The produced acceleration by the brake b. The total angle that the flywheel rotates in 15-s period а.A wheel, initially at rest, starts and rotates trough an angle 100rad with a constant angular acceleration of 2rad/s. What is the angular speed of the wheel at the end of that 100 rad angular displacement? How long did it take the wheel to rotate trough first 50rad?
- Can an object have zero translational acceleration and, at thesame time, have nonzero angular acceleration? If your answeris no, explain why not. If your answer is yes, give a specificexample.A block weighing 100 lbs is placed on arotating platform. The coefficient of frictionbetween the block and the platform is 0.20.Determine the angular velocity that theplatform should be rotated before the blockslips outward if the block is placed 5ft, 8ft, and10ft from the center ofthe platform.A disk of radius R-37.3cm rotates about its central axis through O with a constant angular acceleration X =1.05rad/s2, as shown in the figure.

Express your answer using one decimal place.
- A car is slowing down in a straight road.What direction does its angular velocity point? And what direction does its angular acceleration point?Explanation. A plumb bob is generally to hang vertically downwards – ie, towards the center of the Earth.(it maybe not always true) By drawing a free-body diagram and considering the centripetal acceleration of a plumb-bob (at 45o N latitude), explain why. indicate the direction (north, south, east, or west) that the plumb bob will hang. Two particles execute simple harmonic motion with the same amplitude. One particle has twice the frequency of the other. Compare their maximum velocities and accelerations.Motion in two Dimensions Tangential and Angular Acceleration. A turntable reaches an angular speed of 33.3 rpm in 2.0 s, starting from rest. (a) Assuming the angular acceleration is constant, what is its magnitude? (b) How many revolutions does the turntable make during this time interval?A centrifuge in a medical laboratory rotates at an angular speed of 3,550 rev/min, clockwise (when viewed from above). When switched off, it rotates through 54.0 revolutions before coming to rest. Assuming it is constant, what is the magnitude of angular acceleration (in rad/s)? rad/s?
