Homework Statement
Suppose a skater is sliding down a parabolic track of known height of 12 meters. You are also given the quadratic equation of the track in terms of x and y, which are in meters. Neglecting friction, how would you find the contact force between his wheels and the track at...
Thanks for the reply. The problem says that the disk has an angular velocity of ωi before adding the marble ball in the center. Would adding the marble change the angular velocity since the disk would hence contain more mass?
Homework Statement
The slotted homogeneous disk of mass m freely turns about the vertical axis with angular velocity ωi. A small marble of mass 0.05m is placed near the center of the disk. The marble travels outward along the slot due to centrifugal force. Determine the angular velocity of...
