A body weighing 8 N is supported by two cables whose voltages T1 and T2 form angles of 60 ° and 30 ° with the ceiling. How much are these tensions worth? Choose the correct option. Select one: a. 4N and 7N b. 5N and 7N c. 4N and 10N

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
