# Often asked: What Is The Speed, In M/s, At Which A Car Can Drive Through The Curve If The Road Is Frictionless?

## What is the maximum speed at which a car can round a curve physics?

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.

## When a car rounds a curve on a flat road what supplies the centripetal force that keeps the car moving in a circular path establish the formula for the maximum safe speed of the car?

Since the radial friction with the tires supplies the centripetal force, and friction is nearly 0 when the car encounters the ice, the car will obey Newton’s first law and go off the road in a straight line path, tangent to the curve.

## What is the centripetal force acting on the car?

As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion. As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion.

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

Given Fmax = 245 N and F = mv2/r, we can find vmax. Details of the calculation: vmax2 = Fmaxr/m = (250 N)(0.8 m)/(3kg). vmax = 8.1 m/s.

## Why is it difficult for a high speed car to negotiate an unbanked turn?

An object is said to be non-accelerating when the magnitude of the speed and direction does not alter during its motion. A car negotiating an unbanked road at high speed is actually accelerating as the direction is changing.

## Is centripetal force real?

With this definition, centripetal force would be real and centrifugal not real. Centripetal force is the force needed to make something move in a circle. A constant magnitude centripetal force that is always perpendicular to the direction of motion will make the object move in a circle.

## 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.

## Which force is responsible for holding a car in an unbanked curve?

When a car moves at a steady speed around an unbanked curve, the centripetal force keeping it on the curve comes from the static friction between its tires and the road.

## What is the maximum speed limit for a car to take a safe turn?

Thus, the maximum velocity that can be attained by the vehicle while making the turn is 10.84 m/s.

## What are 3 examples of centripetal force?

Just a few examples are the tension in the rope on a tether ball, the force of Earth’s gravity on the Moon, friction between roller skates and a rink floor, a banked roadway’s force on a car, and forces on the tube of a spinning centrifuge. Any net force causing uniform circular motion is called a centripetal force.

## What is the relationship between centripetal force and speed?

Note that the centripetal force is proportional to the square of the velocity, implying that a doubling of speed will require four times the centripetal force to keep the motion in a circle.

## What is the formula of 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 Max speed?

Maximum speed is the highest rate of speed an athlete can attain. Acceleration refers to velocity, and because velocity has both a magnitude and direction associated with it, acceleration changes when athletes change the magnitude of their motion (how fast they are running), the direction of their motion, or both.
