A race car is traveling at constant speed around a circular track what has to happen to the static friction in order to stay on the track when the speed is doubled?

In that case, the centripetal acceleration - and therefore also the static friction - will increase by a factor of 4.

Is the force of an object doubled if the velocity of an object traveling in circluar motion is doubled holding the radius constant?
If we're going to have this discussion, we need to change the playing field a bit.There's no such thing as the "force of an object". The only force that it makessense to talk about in this situation is the force on the object. That's the forcethat makes the object travel in a circular path, and it's called the "centripetal" force.In order to make an object move in a circular path, a constant force has to act on it,always directed toward the center of the circle. The force could be the tension ina yo-yo string, the friction between the race car and the track, or the gravitationalattraction between a body in a circular orbit and a big mass at the center.If the radius of the path remains constant but you want the object to revolve around ittwice as fast, then it needs 22 = 4 times as much centripetal force to keep it on thecircle, otherwise it skids away to a larger radius.
If normal force is dobledwhat happens to friction?
Frictional force gets doubled. But coefficient of friction does not change
If the frequency of a wave traveling in a rope is doubled what will happen to the speed of the wave?
Assuming that the wavelength remains constant, the velocity of the rope will also double if the frequency is doubled. This can be seen in the word equation below: speed = frequency x wavelength If we assume that wavelength is a constant...let wavelength = 1 speed = frequency therefore... 2 x frequency = 2 x speed
When the contact area is doubled keeping the force acting on the body constant the pressure?
when the contact area is doubled keeping the force constant on the boy, there will be less impact on the body .
How much centripetal force is needed by a body moving in uniform circular motion if the mass is doubled?
If the mass is doubled then the force needed is also doubled,according to the equation F=MV2/R
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
Is fine doubled for speeding in school zone?
Traffic violation fines are generally doubled when the infraction occurs within or traveling through a construction zone.
When the speed of body is doubled kinetic energy becomes?
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.
If a wave is moving at a constant speed and the wavelength is doubled what will happen to the frequency?
IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).
The volume of a circular cylinder varies directly with the height of the cylinder and with the square of the cylinder's radius If the height is halved and the radius is doubled then the volume will be?
The volume of a circular cylinder varies directly with the height of the cylinder and with the square of the cylinder's radius If the height is halved and the radius is doubled then the volume will be increased.
When you double the force acting on an object and keep the mass of the cart constant the acceleration is?
Doubled.
How would pressure change if area is doubled keeping the force constant?
Since P = F/A, PA = F So, if area is doubled, pressure is halved.
