Joaquin mows the lawn at his grandmothers home during the summer months Joaquin measured the distance across his grandmothers lawn as 11.5 meters If Joaquin mows one length across the lawn from east to west in 7.10 seconds then what is the velocity of the lawnmower

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.
