Suppose you increase your walking speed from 5 m/s to 14 m/s in a period of 3 s. what is your acceleration? answer? and units?

Anybody wanna ? (picture included? )

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.

Calculate the volume of this regular solid. what is the volume of the cone? round your answer to the nearest hundredth
