You solve this in two steps.
First, you calculate the centripetal acceleration, using the formula a = v2/r. (Another commonly used formula is omega2 times r, but the first formula is easier to use in this case.)
Second, you use newton's second law: force = mass x acceleration.

What is the centripetal acceleration of an object being swung on a string with a radius of 3 meters at a velocity of 4 meters per second?
Use the formula for centripetal acceleration: velocity squared / radius.
What is the centripetal acceleration of an object being swung on a string with a radius of 5 meters at a velocity of 4 meters a second?
Use the formula a = v2 / r, with v = velocity (speed, actually) in meters/second, r = radius in meters. The answer will be in meters per square second.
How do you calculate the volume of an cylindrical tank?
you calculate the Area of the circle at the end of the Cylinder and then multiply it by the lenght to the second circle at the end of the cylinder Circle area= Radius*Radius* pi pi being 3.14159265
What centripetal acceleration in meters per second squared if it has a twenty eight feet radius and is rotated with an angular speed of ten rpm?
Here are two formulae for centripetal acceleration:a = v2 / r (speed squared divided by the radius)a = omega2r (angular velocity squared, times the radius)The second formula seems simpler to use in this case. Just convert the angular speed to radians per second first. Remember that 1 minute = 60 seconds, and one revolution/second = 2 x pi radians/second.Oh, and you have to convert feet to meters, as well. 1 foot = 0.3048 meters.
If the circumstance of a 1 circle is equal to the diameter of the 2 circle then what is the area of the 2 circle?
let the circumference of the first circle be X. The formula for the area of a circle is pi multiple by radius squared. pi can be y so it is yr2. The radius for the second circle is half the diameter so half X. therefore the are is y(0.5X)2. BTW: is this your homework? :)
What centripetal force is needed to keep a 1 kilogram ball moving in a circle of radius 2 meters at a speed of 5 ms?
In this case, you can use the formula for centripetal acceleration, a =v2/r. Next, use Newton's Second Law to find the corresponding force.
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.
How do you solve for revolutions per second give centripetal force and radius?
One formula is: centripetal force = speed2 / radius. Solve it for speed, then convert that to revolutions per second.One formula is: centripetal force = speed2 / radius.

How does speed affect centripetal force?
Force (newtons) = mass (kg) * acceleration ((m/s)/s) but > acceleration in a circle = velocity 2 / radius So > (centripetal) force = mass * (velocity 2 / radius)
What is the centripetal acceleration of an object being swung on a string with a radius of 3 meters at a velocity of 4 meters per second?
Use the formula for centripetal acceleration: velocity squared / radius.
How is the radius of rotation related to the centripetal force and angular velocity?
Assuming that angles are measured in radians, and angular velocity in radians per second (this simplifies formulae): Radius of rotation is unrelated to angular velocity. Linear velocity = angular velocity x radius Centripetal acceleration = velocity squared / radius Centripetal acceleration = (angular velocity) squared x radius Centripetal force = mass x acceleration = mass x (angular velocity) squared x radius
A satelitte is obriting the earth What is the centripetal accerleration?
a = v^2 / rwhere:a = centripetal acceleration ((metres / second) / second)v = orbital velocity (metres/second)r = orbital radius from earth centre of gravity (metres)
If the maximum tension the rope can withstand before breaking is 126.8 N what is the maximum tangential speed the ball can have?
Not enough information. If the ball moves in a circle, you would also need the radius of the circle, and the mass of the ball.In this case, you can: 1) Calculate the corresponding centripetal acceleration, by using Newton's Second Law (a = F/m). 2) Calculate the tangential speed, using the formula for centripetal acceleration: acceleration = velocity squared / radius.
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.
There is 260g block on a 50cm -long string swings in a circle on a horizontal frictionless table at 50rpm What is the speed of the blockWhat is the tension in the string?
The linear speed will be: v = 2 * pi * r * f, where r is circle radius, f is rotations per second. To calculate tension, we can use formula for centripetal force, which is: F = mv2 / r. This centripetal force will be the tension in the string.
Is it true that When you are driving in a car and turn a corner centripetal force pushes you toward the center of the circle around which you are turning?
Yes. That follows from Newton's Second Law: without a centripetal force, there could be no centripetal acceleration. Since the car accelerates towards the center of the circle, it follows that there must be a force that causes this acceleration.
What is the formula in getting centripetal force and it's net horizontal force?
One formula for centripetal force is v2/2 - the square of the velocity (speed, actually) divided by the radius. Another is omega2r, where omega is the angular speed, in radians/second.One formula for centripetal force is v2/2 - the square of the velocity (speed, actually) divided by the radius.
