During a picnic on a hot summer day all thecold drinks disappeared quickly, and the onlyavailable drinks were those at ambienttemperature of 25ºC. In an effort to cool a 335-ml drink in a can, which is 12.5 cm high andhas a diameter of 6.5cm, a person grabs thecan and starts shaking it in the iced water of thechest at 0ºC. The temperature of the drink canbe assumed to be uniform at all time, and theheat transfer coefficient between the iced waterand the aluminum can is 170 W/m2-ºC. Usingthe properties of water for the drink, estimatehow long it will take for the canned drink to coolto 8ºC.

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
