A heavy turntable, used for rotating large objects, is a solid cylindrical wheel that can rotate about its central axle with negligible friction. The radius of the wheel is 0.330 m. A constant tangential force of 200 N applied to its edge causes the wheel to have an angular acceleration of 0.896 rad/s2. (a) What is the moment of inertia of the wheel (in kg ·m2)? kg · m2 (b) What is the mass (in kg) of the wheel? kg...

really need help immediately with this quesiton! thann you!
A solid metal disk, m=1100.00 kg, r=82.3 cm, acts as a pulley for an atwood machine. The tension from the left side is known to be T -13.4 kN. Once released the pulley accelerates with an angular acceleration of a=3.42 rad/s? in the counter-clockwise direction. What is the magnitude of the tension on the right hand side, T,?

M, a solid cylinder (M=1.39 kg, R=0.111 m)
pivots on a thin, fixed, frictionless bearing. A string wrapped
around the cylinder pulls downward with a force F which equals the
weight of a 0.570 kg mass, i.e., F = 5.592 N. Calculate the angular
acceleration of the cylinder. (the answer to this is 39.8 rad/s^2)
The cylinder is changed to one with the same mass and radius, but a
different moment of inertia. Starting from rest, the mass now moves...

Thanks so much ahead of time!
A spherical shell of radius 0.43 m and mass 27 kg initially rolls without slipping towards an incline at a linear speed of 9.1 m/s. If the ball rolls up an incline (inclined 35 degrees above the horizontal) without sliding. How high will it go? A professor holding a spinning wheel used for a demonstration brings the wheel to a stop by applying a constant, tangential friction force to the edge (his hand). The...
