The 8.1 n weight is in equilibrium under the influence of the three forces acting on it. the f force acts from above on the left at an angle of with the horizontal. the 6.4 n force acts from above on the right at an angle of 46? with the horizontal. the force 8.1 n acts straight down what is the magnitude of the force f? answer in units of n. note i have already gotten this part, which is 5.66n, but i am having difficulties of answering the second portion of this problem, which is: what is the angle of the force f as shown in the figure? answer in units of

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.
