WebSo now, finally we can solve for the center of mass. We've got this right hand side. The left hand side is just gh, that's gonna equal, so we end up with 1/2, V of the center of mass squared, plus 1/4, V of the center of mass squared. That's just equal to 3/4 speed of the center of mass squared. If you take a half plus a fourth, you get 3/4. WebA steel ball with mass 5.0 kg is at rest on a smooth, level surface. A constant force acts on it through a distance of 10.0 m causing it to roll at 25 m/s. What is the magnitude of the force? First, calculate the kinetic energy of the rolling ball.

WebIn terms of masses and velocities, this equation is m1v1x + m2v2x = m1v ′ 1x + m2v ′ 2x. 8.3 But because particle 2 is initially at rest, this equation becomes m1v1x = m1v ′ 1x + m2v ′ 2x. 8.4 The components of the velocities along the x -axis have the form v cos θ . Because particle 1 initially moves along the x -axis, we find v1x = v1.
