4. Joe wishes to hang a sign weighing 7.5 x 10^2 N so that cable A, attached to the store makes a 30 degree angle as shown in the figure
below. Cable B is horizontal and attached to an adjoining building. a)
Draw a free-body diagram showing the forces and tension in the cables
b) Determine the tension in Cable B. *

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.
