If force 1 has a magnitude of 5 N (forward) and force 2 has a magnitude of 30 N (forward), what is the net force acting on the object? A.) 25 N forward
B.) 35 N forward
C.) 25 N backwards
D.) 35 N backwards

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.
