# FAQ: What Is The Minimum Speed In Which The Car Would Fly Off The Road?

## How fast does a car have to go to get airborne?

This gives a rough idea of the wind speed required to lift a car into the air during the passage of a tornado. If the car weighs a tonne and has a side area of 5 m2, for instance, the wind needs to be at least 39 m/s, or 141 km/h.

## What is the minimum speed of the car if it loses contact with the ground at the top of the hill?

For the car to lose contact with the road, it must be traveling at a speed of 28 m/s or greater when it reaches the crest of the hill.

## How do you find minimum speed in circular motion?

The minimum or critical speed is given by vcritical=√rg. This is the point where the normal (or tension, frictional, etc.) force is 0 and the only thing keeping the object in (circular) motion is the force of gravity.

20 m/s.

## Is a car a projectile?

When an object has a motion due to gravitational force alone, it’s called projectile motion. When a car hits this buckle in the highway, it is launched with some initial velocity and at some angle above the horizontal.

## How do cars become airborne?

@TheOrangeCone asked why Kurt Busch went airborne in the Talladega crash. The answer is the same for all the cars that end up in the air: when a car rotates (so that its side or its back is leading instead of its front), it looks an awful lot like an airplane wing — a shape that is optimized to generate lift.

## What is the centripetal force of a car on a hill?

When the car goes over a hill the centripetal force which causes the car to travel in a circular path is the difference between the weight and the support force. As the car’s weight is providing the centripetal force, then as the car gets faster then S must get smaller and smaller until it reaches 0.

## What is the normal reaction on the car if it passes the top of a hill?

When the car is at the top of the hill, the reaction force is vertically upwards and the weight is vertically downwards, thus the resultant of the two that acts towards the centre of the circular path = mg – R. This resultant force provides the centripetal force and so mg -R = mv2 /r.

## What is the car’s speed at the top?

World’s Fastest Cars

• SSC Tuatara: 316 mph.
• Bugatti Chiron Super Sport 300+: 304 mph.
• Hennessey Venom F5: 301 mph*
• Koenigsegg Agera RS: 278 mph.
• Hennessey Venom GT: 270 mph.
• Bugatti Veyron Super Sport: 268 mph.

## What is tangential acceleration formula?

The tangential acceleration = radius of the rotation * its angular acceleration. It is always measured in radian per second square. Its dimensional formula is [T2]. When an object makes a circular motion, it experiences both tangential and centripetal acceleration.

## How do you find the minimum tangential speed?

Divide the circumference by the amount of time it takes to complete one rotation to find the tangential speed. For example, if it takes 12 seconds to complete one rotation, divide 18.84 by 12 to find the tangential velocity equals 1.57 feet per second.

## What is the formula for maximum speed?

The formula for speed is simply v(0)t. 19.8*15.9= 314.82 m/s for the maximum speed.

## What is the maximum speed a car can go around a curve?

The maximum speed at which the car can negotiate this curve is 25 m/s. Car B uses tires for which the coefficient of static friction is 0.85 on the same curve.

## Is friction force always negative?

Insight: Kinetic friction always does negative work because the force is always opposite to the direction of motion.

## What is the maximum speed with which a car can round a turn of radius?

Putting the values of the parameters and g= 9.8m/s, we get, v=√μgR=√0.4×9.8×30=√117.6=10.84. Thus, the maximum velocity that can be attained by the vehicle while making the turn is 10.84 m/s.
