Hello I need help on questions 5,6, and 7. Work would be appreciated if possible!

5. [I2 Points] SERPSE10 10.2.0P.004.MI. 0/6 Submissions Used ASK YOUR TEACHER An electric motor rotating a workshop grinding wheel at 1.20 x 102 rev/min is switched off. Assume the wheel has a constant negative angular acceleration of magnitude 2.08 rad/52. (a) How long does it take the grinding wheel to stop? :5 (b) Through how many radians has the wheel turned during the time interval found in part (a)? rad Need Help? _ _ 6. [-/1 Points] DETAILS SERPSE10 10.2.OP.007. 0/6 Submissions Used MY NOTES ASK YOUR TEACHER A brake is applied to a rotating flywheel, initially moving counterclockwise, causing it to slow down with a constant angular acceleration of magnitude 5.00 rad/s. Immediately after the brake is applied, the flywheel rotates through 57.9 rad during a 4.00 s time interval. What is the angular speed (in rad/s) of the flywheel at the end of this time interval? rad/s Need Help? Read It7. [l2 Points] DETAILS SERPSE1O 10.2.P.003. 0/6 Submissions Used A wheel starts from rest and rotates with constant angular acceleration to reach an angular speed of 11.4 rad/s in 3.08 s. (a) Find the magnitude of the angular acceleration of the wheel. Em (b) Find the angle in radians through which it rotates in this time interval. Need Help
