    Solving Drag Racing Problem: Who Wins and By How Much Time?

    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...

    Hot Wheels Racing: Factors for Fast Cars & Modifications

    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!

    Questions related to racing and physics

    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...

    Kinetic Energy in Racing Question

    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...

    Racing & Objects: Can Fastest Lose Race? Difference b/w Speed & Accelaration?

    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

    Racing car example to do with coefficient of friction

    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...

    Photon and electron racing show

    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...

    Racing car centripetal force problem

    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?

    Should NASCAR be taxed for wasting fuel?

    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.

    Electric Drag Racing - National Association (NEDRA)

    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...

    Formula one racing car question.

    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 ?

    The whole racing with light thingy.

    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...
