Vodka an alcoholic beverage is a 50-50 mixture of ethyl alcohol and water. If a person buys 50 liter of vodka at $8 per liter at -5 °C and sells it at $8 per liter at 40 °C. How much profit you will the person make. The volume coefficient of ethyl alcohol
and water are 7.5x 10-40c-1 and 2.1 x 10-4 0-1

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.
