A ball of mass m is thrown straight up in the air with an initial speed v_0.
a). Find an expression for the maximum height reached by the ball in terms of v_0 an g.
b). Using conservation of energy and the result of part (a), find the magnitude of the momentum of the ball at one-half its maximum height in terms of m an v_0.
A collapsible plastic bag contains a glucose solution. If the average gauge pressure in the vein is 13900 Pa, what must be the minimum height of the bag in order to infuse glucose into the vein? Assume that the specific gravity of the solution is ..
