Determine the angular acceleration of AB and the linear acceleration of A for the position = 90° if = 2.4 rad/s and = 0 at that position. The angular acceleration of AB is positive if counterclockwise, negative if clockwise. The acceleration of A is positive if to the right, negative if to the left.

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
