Cars and Transportation

I have a 8 year old son. I use to be into radio control cars, the kind that you would get from a Hobby Shop. But I want to buy something for my son that would be fast but not hobby shop expensive. How do the ratings work with mhz and battery voltage as far as speed?
Doesn’t voltage on the battery effect that as well?

Some have lights on the dash/deck+on the roof.
Some have lights on the dash/deck only.
Some have lights on the roof only.
All of the cop cars are marked by the way.

This was just a random thought of mine. Most cars can attain maximum speeds of 180mph, but maximum speed limits are usually 60-65 mph. If cars could me made to drive lower speeds, will the roads be safer?

In a road accident where one car has stuck to another on collision, accident investigators often measure the length of skidmark produced from where the vehicles collided. The mass of the two cars and the deceleration produced by the road are also measured. How can these figures be used to calculate the velocity of te cars before collision? I got this question as homework after having had a Physics lesson on Momentum. Any help will be very much appreciated. Thanks.
Thanks for all the responses. The question says that you are given the mass of the 2 cars, the deceleration after collision and the length of the skidmark.
Cons. of momentum means that total before = total after. So basically,
m1*v1 + m2*v2 = m3*v3.
So I have m1 m2 and m3 as well as v3 (which can be worked out using the suvat equation v-squared = u-squared + 2as.) As a class we haven’t gone into any details regarding friction and kinetic energy, and are just supposed to use the suvat equations and the law of conservation of momentum to answer this question. Please help!
What I’m supposed to work out is v1 and v2.

Hi! What are some cars equipped with automatic transmissions that offer the best price to performance ratio?

I was in a low speed crash with a Prius and wonder if that type of car has a higher probability of being totaled than cars more traditionally engineered.

What are those video loop things of like a city and cars driving and everything in fast motion? Some people have them on their myspaces. If anybody knows what they are called and/or a website i can find them that would be greatly appreciated.

I have heard of this but what is the update on this situation. Are there specific cars that can go in the lane? Is this law now out of date?

I went and washed my car yesterday, like I do every week and when the car dried, I noticed there are surface scratches all over from the bubble brush. I am looking for the best way to remove these scratches. I wash two cars every week with the same method and this have never happened before. Help!!!!
