A bicyclist of mass kg rides in a circle at a speed of 4.5 ms. If the radius of the circle is 8 m what is the centripetal force on the bicyclist?
The centripetal force acting on the bicyclist is equal to the centripetal acceleration multiplied by the mass of the bicyclist. The centripetal acceleration is given by v^2 / r, where v is the speed of the bicyclist and r is the radius of the circle. Plugging in the values, the centripetal force can be calculated as F = m * v^2 / r.
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 net force of 7 newtons left and 2 newtons right?
The net force is 5 newtons to the left (7 N - 2 N = 5 N).
What is the meaning of centripetal force?
Answer It is the force which keeps a body moving in circular motion. Centripetal force is the force that acts opposite to cetrifugal force. Centripetal force is a real force. Centrifugal force is a pseudo-force
What is the formula for the centripetal acceleration force of a mass?
The formula for centripetal acceleration is a = v^2 / r, where a is the centripetal acceleration, v is the velocity of the object, and r is the radius of the circular path. The force required to produce this acceleration is given by F = m * a, where F is the centripetal force, m is the mass of the object, and a is the centripetal acceleration.
What is A 0.25 kg stone tied to a 0.5 m string whirls at a speed of 4 m s What is the centripetal acceleration acting on the stone?
Centripetal acceleration = V2/R = (4)2/(0.5) = 32 meters/sec2The centripetal acceleration doesn't depend on the stone's mass.(The centripetal force does.)The centripetal acceleration doesn't "act on" the stone.(The centripetal force does.)The centripetal force acting on the stone is F = M A = (0.25) (32) = 8 newtons.

Does gravity zero at equator according to centripetal force explain?
gravity provides pretty much the same force on a given mass anywhere on earths surface, due to its mass only and irrespective of earth spin. example: say your 70 kg mass at equator (where centripal action is greatest) force due to gravity : f = (G*m1*m2)/d^2 = 687.4 newtons force due to centripetal action at equator : f = mass * (v^2/r)= 70*0.034 = 2.38 newtons

What is centripetal force and write its formula?
Centripetal force is the force that keeps an object moving in a circular path. Its formula is Fc = (mv^2) / r, where Fc is the centripetal force, m is the mass of the object, v is the velocity of the object, and r is the radius of the circular path.
How is centripetal force affected by mass?
Centripetal force is not affected by mass. The formula for centripetal force is Fc = (mv^2) / r, where m is mass, v is velocity, and r is the radius of the circular motion. The mass only affects the inertia of the object in circular motion, not the centripetal force required to keep it moving in a circle.
What is the relationship between the velocity of an whirling object and the centripetal force that is exerted on it?
The velocity of a whirling object is directly proportional to the centripetal force exerted on it. As the object moves faster, the centripetal force required to keep it in circular motion increases. The equation for centripetal force is Fc = (mv^2)/r, where m is mass, v is velocity, and r is the radius of circular motion.
If the radius of rotation and the mass being kept constant how does the centripetal force vary with the speed of rotation of the body?
Recall centripetal force = m v^2 / rAs m and r are found to be constants then centripetal force F is directly proportional to the square of the velocity of the body
A car with a mass of 1200 kilograms is moving around a circular curve at a uniform velocity of 20 meters per second The centripetal force on the car is 6000 newtons What is the radius of the curve?
80 meters. Since the only force on the car is centripetal force then:Fc = macac = v2/rFc = (mv2)/rSolve for rr = (mv2)/Fcr = (1200)(20)2/(6000)r = 80m(See my work in the link below.)
