For the following exercises, find the mass of the two-dimensional object that is centered at the origin. 253.A cone-shaped tank has a cross-sectional area that increases with its depth: A = ( π z r 2 h 2 ) / H 3 . Show that the work to empty it is half the work for a cylinder with the same height and base.

The 0.50 lb ball is shot from the spring device shown. The spring has
a stiffness k = 10 lb/in. and the four cords C and plate P keep the
spring compressed 2 in. when no load is on the plate. The plate is
pushed back 3 in. from its initial position.
(Eigure 1)
If it is then released from rest, determine the speed of the ball when it travels 23 in. up the smooth plane.
