The buoyancy acceleration is critical to the formation of thunderstorms and their associated hazards. The maximum vertical velocity attained depends on the vertical distribution (magnitude and depth) of positive buoyancy experienced by a rising air parcelwithin the storm. Consider two environments, one with positive buoyancy in a layer that is 6 km deep and the other with positive buoyancy in a layer 12 km deep. The 6-km deep layer has an average parcel-environment temperature difference of 4 K, while the 12-km deep layer has an average parcel-environment temperature difference of 2 K. The temperature at the bottom of the layer in both environments is 300 K and the average environmental lapse rate is 6 K km-1. a. Determine the maximum vertical velocity experienced by a rising air parcel in each environment. Which environment has the greatest w? b. Show that the maximum vertical velocity from a can also be found using a relationship that depends on convective available potential energy (CAPE): w = 2 CAPE

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.

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
