If 250 feet are required to stop a car traveling 60 miles per hour,how many feet are required to stop a car traveling 96 miles per hour?
Assuming a constant effective braking force (hence acceleration), the braking time is in direct variation with the initial speed. Suppose that T seconds are required in the 60 mph case. Then 96T/60 is required in the second case. 96 mph breaking distance = (1/2)a(96T/60)² = (1/2)aT²(96/60)² = 250(96/60)² = 640 feet Another way to look at it, braking distance times the braking force is the work done by the brakes, which is equal to the initial kinetic energy of the car. The kinetic energy is in direct variation with the square of the velocity. Again assuming constant force, the braking distance must also vary directly with the square of the velocity.
Whats the Best Car to Lease?
First of all, you need to decide if buying or leasing is best for you. If you are inclined to keep your car until the wheels fall off, then buy. If you put more than 12,000 to 15,000 miles per year, then buy. If you are the type who likes to buy a car every 3 to 4 years, and puts under 12,000 miles a year, then lease. Leasing payments are based on the residual value(what the car is worth at the end of your lease) The HIGHER the residual, the lower the payment for the same PRICED car. For instance, take any $10,000.00 car. If after 4 years, that car's residual is $5,000.00 your payment is based on the remaining $5,000.00 plus interest over a 4 year period. When the car is returned after the 4 years, they will re- sell that car for at least $5,000.00 plus. Say another car selling for $10,000.00 has a residual value for $3000.00. Your lease payment will be based on the remaining $7000.00 plus interest over a 4 year payment. Which car will have the lower payment? The first one. The interest charged is based on your credit score. The higher the score, the lower your interest rate is. It is harder to lease a car than to buy it for credit reasons. You still have to maintain the car as if you own it. If the car is beat up more than what is considered usual you will be charged what it will take to bring the car to what is considered usual and customary. The best time to lease a new car is in September when the new model year comes out because that is when it has the highest resale value (residual). As time passes, the residual lowers because the car ages. When the residual lowers, the payment is higher. Yes, Hondas are a good car to lease because the residual value is extremely high.
Why are electric cars better for the environment?
They are not better for the environment unless the electrical energy that powers them comes from a less environmentally depleting source than the gasoline. Gasoline is a very streamlined fuel for a car's purpose, but there is more than crude oil as a cost of our using it. Electricity is thought to be the future's storehouse of energy because more carbon conserving ways of generating power often are readily electrical , like rubber shoes on acrylic carpets. Note that P.E. of electicity is ready-to-generate electricity and not that storage of actual energy is battery dependent and very technically limited. Fetching an asteroid and yo-yoing it on the edge of our atmosphere creates some charge. What's a shovel -full of air gonna hurt? Oops, sorry you continent ,you.
I am earning 90,000 per month in india, and I want to buy my first car, how can I buy? Can a person who earns 90,000 afford a car worth 7-9 lakhs?
I would like to give you a different perspective. I would suggest buy a car that would cost you up-to maximum of 50% of your yearly salary.You have mentioned (Your First Car) so can I safely assume this will be the car that you will be learning driving on, just after you get your driving license?Key Reasons for this:A low cost car (could be a new one or a second hand premium car) would hurt you less when you have scratches, dents on it.You could use this for 2 years till you gain expertise and have dented the car during your learning period.Cost of insurance is building up. For smaller cars it could be between 8-12k, and the premium goes up as the cars price goes up. No one really cares what car you drive, unless you have extreme social pressure of owning an expensive car. You will not mind lending your car to your friend, neighbour, colleague knowing its just a means of transport (lower investment on the car).After 2 years, given your salary goes up to 15 LPA, you will think of buying a larger car or decide to stick to the present car itself.And if you are in Delhi, you may think of buying another car after 2 years with a (Odd/Even) number that you may need to :-)P.S: I have only bought second hand cars throughout which cost me less than a half years pay always. I pay less when I buy, I loose less when I sell!
Best type of insurance for car? (Read details)?
Hey there guys. Just picked up a 2001 Volkswagen Jetta 5-speed manual for $100 and a few other things I traded him. What insurance would be good on a car like this? Pay per mile? A deductible plan (like state farm or country financial)? the car would not be driven probably not even 300 or 400 miles a month, as this is a second car (my 2012 ford focus SEL hatchback is my main daily). Thanks guys!
What is a good luxury car to own that does not require changing the timing belt?
I currently own a 1998 Acura RL and although I love the car it is recommended to have the timing belt replaced every 90,000 miles at a cost of $1,800. What are some luxury cars that are similar to the Acura RL that do not require the replacement of a timing belt? Lexus? Infiniti? I usually buy 4 or 5 years used.
If it costs $700 per car or truck to install seat belts and all people are required to use them when in the ve?
The whole question is "If it costs $700 per car or truck to install seat belts and all people are required to use them when in the vehicle, what is the cost of each life saved if the use of a seat belt reduces the probability of being killed by 30%. Assume that 0.6 of the present 25,000 vehicle occupants killed in collisions were not wearing seat belts. There are about 170 million registered cars and trucks on the highway today." I got a hint that said to Assume the average car life is 10 years" I calculated it using all the information but my answer just came out wrong. Could someone help me out?
