Abe can paint the room in 15 hours, Bea can paint 50% faster than Abe, and Coe can paint twice as fast as Abe. Abe begins to paints the room and work alone for the first hour and a half. Then Bea joins Abe, and they work together until half the room is painted. Then Coe joins Abe and Bea, and they work together until the entire room is painted. Find the number of minutes after Abe begins for the three of them to finish painting the room. *

Short Answer: Consider Z Z Z D f(x, y, z) dV where D is the solid shown in the figure below. Is it easier to write an iterated integral using dz dy dx or dx dz dy? Hint: You can answer this without actually setting up either integral

A ball is thrown from the top of a building with an initial velocity of 20.0
m/s straight upward, at an initial height of 50.0 m above the ground. The
ball just misses the edge of the roof on its way down, as shown in the
figure. Determine (a) the time needed for the ball to reach its maximum
height, (b) the maximum height, (c) 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) the time needed for the ball to reach the ground,
and (e) the velocity and position of the ball at t = 5.00 s. Neglect air drag.
