A part of a subway train's journey is captured using a motion detector and displayed on the graph shown. Use the graph to answer the following questions. Right is defined as positive. Answers have a 5% tolerance to allow for estimation. Describe the subway train's direction of travel: neither Describe the subway train's motion: at rest What is the distance traveled?What is the final speed?

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.
