1. The problem statement, all variables and given/known data A 12 Volt lead-acid car battery, engineered for "up to 500 or more charge/discharge cycles," has a rating of 330.0 Ampere-hours.
1. The problem statement, all variables and given/known data A 12 Volt lead-acid car battery, engineered for "up to 500 or more charge/discharge cycles," has a rating of 330.0 Ampere-hours. It sells for $ 262.00. Part B: The battery has a mass of 32.7 kg. What total mass of such batteries would be required to deliver the same effective mechanical energy as 16.0 gallons of gasoline? Assume that the efficiency of an electrically powered car is 2.5 times that of a gasoline-powered car for the conversion to mechanical energy. DATA: Energy content of 1 gallon of gas = 1.32 x10^8 Joules. For Part A, we were to find the total electrical energy that the battery can deliver before needing recharged, but I was able to find that. 2. Relevant equations I really do not know what equation is necessary... F=ma or 1/2mv^2 maybe? 3. The attempt at a solution I am very stuck on the basic principles here. I believe I need to set up a ratio and then solve for mass, but what equation is necessary?
