Sam Peltier asked: My physics lab requires me to find the mass of a van without turning it on. My group can move the car, but we cannot turn it on. We can use the following items:
-3 Bathroom scales
-1 Stopwatch
-1 Measuring tape
I have to incorporate friction. To find the friction coefficient, we will push the car at a constant velocity with the bathroom scales between us and the car. The total force shown on the scales will be the amount of force needed to overcome friction resistance. I do not know what to do after that.

Pedro asked: I have been reading a number of articles about changing to hydrogen cars and how it would result in a decrease in pollution. While it is true a hydrogen car would be a number of times cleaner than a regular gas car, I have a few doubts about how clean the hydrogen making process would be. If hydrogen obtained from water, wouldn’t it require a great deal of energy to get the hydrogen out of it? Wouldn’t the energy required to do this come from oil and the more traditional non-green energy sources? Overall, is the process for obtaining enormous amounts of hydrogen overall green at all?

Rex asked: I had a graphing question on a quiz that asks “The year the car was made and it’s total mileage” and then asks if it is a positive or negative graph. Of course, I put positive because the older the car is, the more it’s probably been driven. My teacher insists that mileage means how many miles a car has left before it starts to die.

Thatchick06 asked: I drive a late model car and for some reason the door is filling up with water. I don’t know how to fix it or even what type of “car person” to take it to. Any ideas?

Alexander G asked: I am 15 years old. I know that you can get your permit when you are 15 and a half. I turn 15 and 6 months in March of 2010. First of all, I would also like to know how a permit works. I am an identical triplet, my mom cannot afford insurance for all of us. We have a 1985 BMW and we are preparing mechanical alternations on it. How can we all have car insurance to cover our payments?

huntertristan asked: My mother always revs up the car and drives it a high speeds of 20-30 before going into 2nd gear and then when getting to 35-40 will go into third. She never uses forth gear. I am convinced she will ruin the car by driving this way. In fact the last 2 cars our family had just suddenly gave up after 6 years or so. After observing my mother’s driving method, I wonder do I now have the reason why this happened?
