1. The specific heats of aluminum add iron are 0.214 cal/(g*Celsius) and 0.107 respectively. If we add the same amout of energy to a cube of each material ( of the same mass) and find that the temperature of the aluminum increases by 33 degrees Fehrenheit, how much will the iron temperature increase in degrees Fahrenheit.

2. When we drive our car at 100 feet per second, we measure an aerodynamic force ( called drag) of 62 pounds-force that opposes the motion of the car. How much horsepower is required to overcome this drag?


If someone can answer this?
