Question
Hello. This is multiple choice so you can give me the letter of the answer. Thank you!! This is 1 question it just has 3 parts..
D. 125 A record on a turntable is spinning and coming to rest. At t=0 s. the angular velocity of the record is 20.0 rad/s with a constant acceleration of-5.00 rad/s. What is the record's angular velocity at t = 0.500 s? A. 10.5 rad/s B. 15.5 rad/s C. 16.5 rad/s D. 17.5 rad/s A A tire is rolling with an initial angular velocity of 10.0 rad/s. It slows down with an angular acceleration of -5.0 rad/s and comes to rest. What is the net angular displacement of the wheel? A. 5 rad B. 10 rad C. 25 rad D. 30 rad 12h A solid cylinder consisting of an outer radius R1 and an inner radius R2. A string is wound around the outer radius and is pulled to the right with a force F1 = 3N. A second string is wound around the inner radius and pulled down with a force F2 = 5N. If R1 = 0.75m and R2 0.35m, what is the net torque acting on the cylinder? (+ direction is counterclockwise) F1 a) 2.25 Nm b) -2.25 Nm c) 0.5 Nm d) - 0.5 Nm e) O Nm
