I have a problem in my D.E. class that is driving me nuts. Two drivers, A and B are in a race. Beginning from a standing start they both proceed at a constant acceleration. Driver A covers the last 1/4 of the distance in 3 seconds. Driver B covers the last 1/3 of the distance in 4 seconds...

Homework Statement Hello my name is Luke , This may seem random but i need your help as I am a hardcore Horse Racing fan and need to come up with a rating tool to rate horse's so i can sort the average horses from the good ones and I have been coming up with all sorts of calculations...

I'm interested in the physics behind racing Hot Wheels cars. When you release the cars from an incline, what makes some cars go faster than others? What would be the most important factor of a fast car (ex. weight, aerodynamics, etc.)? How could I modify a car to go faster? Thanks!

I have tried finding these answers on the internet, but I believe I simply don't know enough about physics (I got a D in high school) to really know what it is I'm supposed to be looking for. I'm working on a game that will simulate drag racing. As I want the game to be as realistic as...

Estimate the maximum pressure that would be applied to your hand if oyu were told it out of an open car window while the car travles at 70mph through still ait at 20 degrees c what would be the maximum pressure applied to your hand if the car where a formula one race car traveling at 220mph I...

Hello, I have this Physics problem that's due tomorrow in class and I'm having some troubles with it. Homework Statement PROBLEM: A racing car has a mass of 1500kg is accelerating at 5.0m/s^2, is experiencing a life force of 600N up (due to its streamlined shape) and group effects of 1000N...

The good old days of Formula 1.

Homework Statement A dragster of mass m races another a distance d from a dead stop. Assume a constant instaneous power P for the entire race (provided by engine) and the dragster is like a particle. Find the elapsed time for the race. Homework Equations Well, P = Fv is needed for...

All right, here is the question A father racing his son has 1/3 the kinetic energy of the son, who has 1/3 the mass of the father. The father speeds up by 1.6 m/s and then has the same kinetic energy as the son. So to being with, I set up two equations equal to each other, since the only...

i need some help on these two question is it possible for the with the highest speed crossing the finish line to lose the race? why if one object has a higher speed than the second one then does it mean the first one has a higher accelaration? thanks

A racing track has a corner which is banked at an angle of 30 degrees cars passing round the corner travel in an acr of a circle of radius 20 metres. car is traveling at 30 m/s and using g as 10 instead of 9.81 I need to find the smallest value of the coeffiecent of friction needed to...

Say I was watching a photon and an electron are racing (ignore other physics factors), :cool: the photon is moving away from the electron at a constant speed, v. Since the show plays too fast for me, so I slowed down the movie and re-watch the show again.:cool: In common sense, both...

Hi All I'm trying to creater online racing game based on car physics. My car already running on the straight, but as you know racing tracks had some corners (doh !). How my model pass the corner you can find in this tread https://www.physicsforums.com/showthread.php?t=117606" But As i know...

a racing car is traveling on a circular course of radius 641m at a speed such that it makes 1.7 rev in 1 minute. THe mass of the car is 1990kg. what is the centripetal force acting on the car? CF=ma=mass*acceleration a=V^2/r how do you find v?

NASCAR is annoying enough, without the figure that over 5% of the nation's gasoline supply (a large percentage of what we are forced to import) is wasted on the non-sport of auto racing. It's time we taxed some sensibility into this American-antithetical conspicuous consumption.

There is actually a national association for this. http://www.nedra.com/ The specific energy (Watt-Hrs/kg) of gasoline and hydrogen are quite high (which is why we drive with gasoline) compared to batteries or flywheels which have ~100 times lower specific energy. The specific...

I have read that an f1 racing cars fairings produce 2 tonnes of downward force to keep the car stuck to the track. The car weighs 500 kilos so if the track were to be somehow turned upside down while the car was at speed would it fall ?

Einstein imagined what would it be like if one would race with light. For the racer, it seems that the light sped away from him at c. But at an intertial frame of reference, the guy seemed to be catching up with the light beam. But, is it possible for the stationary observer to see the racer...

hey everybody, I am new to the forum, and glad to be here. looks like a great place for help when all has failed! :cry: if you race 2 cans of broth down a ramp, one frozen and one still liquid, which one wins? well, i did this mathematically, using the equation for a solid ring...

Hey guys, have a question for you that I cannot get passed while laying out a track idea for the October races. The Elements: RC length/weight = 16 inches/7-10 pounds Total Track length = 44 feet (including ramp) Total Ramp length/height = 20 feet/20 inches End of Ramp to landing zone =...

I'm an EE trying to learn the basics of fluid dynamics and CFD, due to my interest in car racing. Currently I'm looking at the flow through exhaust systems to get a feel for what allows the most airflow and therefore the most horsepower. I set up the problem by forcing a boundary condition at...

why is the human race commiting suicide? we tell ourselfs that we are advancing but we are doing everything to kill each other as well as comit suicide weather directly or indirectly , comments please

A racing car moves on a circle of constant radius b.If the speed of the carvaries with time t according to the equation v=ct where c is a positive constant, show that the angle between the velocity vector and the acceleration vector is 45 degree at time t=(b/c)^1/2

After reading a thread on this forum i thought that this would make a good thread for people to discuss who they feel is the best racing driver ever. This could be a Formula 1, Indy, Nascar or any other profesional racing driver. Dont want any fools claiming to be a better driver when nobody has...
