Answer #1

angular speed = 2pi*N / 60

N = 10 / 10 = 1 rpm

w = 2pi*1 / 60 = 0.105 rad/s

centrifugal force = mrw^2

where m = mass of the object

r = radius

w = angular speed

F = 2*50*0.105^2

= 1.1 N

so the centrifugal force is 1.10 N

    body of mass 7 kg moves in a (counterclockwise) circular path of radius 4 meters, making one revolution every 13 seconds. You may assume the circle is in the xy-plane, and so you may ignore the third component. how do you find the centripetal force acting on the body how do you find the magnitude of the force??

  • An object of mass m moves at a constant speed v in a circular path of radius r.

    An object of mass m moves at a constant speed v in a circular path of radius r. The force required to produce the centripetal component of acceleration is called the centripetal force and is given by F=mv2/r. Newton's Law of Universal Gravitation is given by F=GMm/d2, where d is the distance between the centers of the two bodies of masses M and m, and G is a gravitational constant. The speed required for circular motion is v= √(GM/r). Use the...
