Magnitude of centripetal acceleration is given by a = v2/r

Converting 400 kmh-1 in ms-1 we get 111.11 ms-1

Therefore, a = (111.11 ms-1)2/200 m = 12345.4321 m2s-2/200 m = 61.7271605 ms-2

How does centripetal acceleration depend upon the object's speed and the radius of the circle?

Centripetal acceleration is directly proportional to the square of the object's speed and inversely proportional to the radius of the circle. This means that as the speed of the object increases, the centripetal acceleration increases, while a larger radius decreases the centripetal acceleration.


What will be the accelaration of a car moving in circle with uniform speed?

The acceleration of a car moving in a circle with uniform speed is directed towards the center of the circle and is called centripetal acceleration. This acceleration is given by the formula a = v^2/r, where v is the speed of the car and r is the radius of the circle.


How do you calculate speed moving around the curve?

To calculate the speed of an object moving around a curve, you can use the centripetal acceleration formula: (a = v^2 / r), where (a) is the centripetal acceleration, (v) is the speed of the object, and (r) is the radius of the curve. To find the speed ((v)), you need to know the radius of the curve and the centripetal acceleration acting on the object.


If you increase the radius of circular motion then what is the centripetal acceleration?

That depends what you will remain constant: the angular velocity, or the speed. Here are two formulae that can help you decide: acceleration = speed squared / radius, and acceleration = angular velocity squared times radius. Angular speed should be measured in radians in this case. Angular speed is equal to 2 x pi x (revolutions per second). From the above formulae, it clearly follows that: (a) If you maintain the speed constant (and thereby reduce angular speed, a larger radius means less centripetal acceleration. (b) If you maintain the angular speed constant (and thereby increase the speed), a larger radius means more centripetal acceleration.


An object traveling a circular path of radius 5 m at constant speed experiences an acceleration of 3 ms2. If the radius of its path is increased to 10 m but its speed remains the same what is its acce?

If the speed remains the same and the radius is doubled, the centripetal acceleration will be halved. The centripetal acceleration is inversely proportional to the radius, so doubling the radius will halve the acceleration. Therefore, the new acceleration will be 1.5 m/s^2.

How does the centripetal force with the speed of rotation of the body with constant mass and radius of rotation?

You can calculate the centripetal ACCELERATION with one of these formulae: acceleration = velocity squared / radius acceleration = omega squared x radius Acceleration refers to the magnitude of the acceleration; the direction is towards the center. Omega is the angular speed, in radians per second. To get the centripetal FORCE, you can use Newton's Second Law. In other words, just multiply the acceleration by the mass.


How to find maximum centripetal acceleration?

That depends on the situation, on the problem you are trying to solve. If speed is constant, maximal centripetal acceleration occurs where the radius of curvature is smallest - for example, in the case of a parabola, at its vertex. If the radius of curvature is constant, maximum centripetal acceleration occurs when the speed is greatest (for an object reacting to gravity, that might be at the bottom of a circular path). In other cases, you have to get a general expression for the centripetal acceleration, and maximize it (using methods of calculus).


How do they affect the centripetal force?

If an object moves in a circle, the centripetal acceleration can be calculated as speed squared divided by the radius. The centripetal force, of course, is calculated with Newton's Second Law: force = mass x acceleration. Therefore, the centripetal force will be equal to mass x speed2 / radius.


What is the difference between centripetal acceleration and radial acceleration?

Centripetal acceleration is the acceleration directed towards the center of a circular path, while radial acceleration is the acceleration directed along the radius of the circle. In simpler terms, centripetal acceleration keeps an object moving in a circle, while radial acceleration changes the speed of the object.


What is the relationship between constant acceleration a speed v and distance r from the origin for a particle travelling in a circle?

For a particle traveling in a circle at a constant speed, the acceleration is toward the center of the circle, known as centripetal acceleration. The acceleration is determined by the formula a = v^2 / r, where v is the speed of the particle and r is the distance from the origin (radius of the circle). This relationship shows that as the speed or radius changes, the centripetal acceleration will change accordingly.


What is centripetal acceleration equation?

Two equations are commonly used for the magnitude of the centripetal acceleration (the direction of the acceleration is towards the center): a = v squared / r a = omega squared x r where: * v is the linear speed * omega is the angular speed (in radians/second) * r is the radius


How do you calculate the centripetal acceleration of an object?

ac = v2/r, where the variables are: * 'a' is the centripetal acceleration in metres per second per second; * 'v' is the tangential velocity in metres per second; and * 'r' is the radius of motion in metres.
