Your 200g cup of coffee is boiling hot (100 degrees celcius). You throw in 50g of -15 degrees celcius of ice to cool it off. Assuming negligible heat leaves the coffee-ice system during this process, what is the final temperature of your coffee? (The specific heat capacity of ice is 2.03 J/(g degree C and the specific heat capacity of water is 4.18 and the latent heat of melting for ice to water is 334J/g).

QUESTION 10 Assume that you have 40 years until retirement and have just started your first job. Once you retire, you anticipate that you will live for 30 additional years. Assume that you will require $100,000 per year to support yourself in retirement. All investments that you make will go into and stay in an account that returns 0.046 per year (i.e. however much you have at retirement will sit in that account and continue to accrue interest on the...
