**A physicist, upon awaking one morning to find his stove out of order, decides to boil the water for his wife's coffee by shaking it in a thermos flask. Suppose that he uses 380 cm3 of tap water at 58°F, that the water falls 1.15 ft each shake, and that the physicist completes 32 shakes each minute. Neglecting any loss of thermal energy by the flask, how long must he shake the flask before the water boils?**

Could anyone give me alittle help as to what equation to

use for this problem?
