Apulley of radius r and moment of inertia i = 2 mr2 is mounted on an axle with negligible friction. block a with a mass m and block b with a mass 3m are attached to a light sting that passes over the pulley. assuming that the string doesn’t slip on the pulley, answer the following questions in terms of m, r, and fundamental constants a. what is the acceleration of the two blocks? b. what is the tension force in the left section of the string? c. what is the tension force in the right section of the string? d. what is the angular acceleration of the pulley?

Ithink your answer is d

Hey can someone me with my homework

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
