A solid ball of mass m rolls along a horizontal surface with a translational speed of v. What percent of its total kinetic energy is translational?
Answer to relevant QuestionsEstimate the ratio of the translational kinetic energy of the Earth as it orbits the Sun to the rotational kinetic energy it has about its N– S axis. A cylindrical hoop, a cylinder, and a sphere of equal radius and mass are released at the same time from the top of an inclined plane. Using the conservation of mechanical energy, show that the sphere always gets to the ...A 10-kg rotating disk of radius 0.25 m has an angular momentum of 0.45 kg ∙ m2/s. What is the angular speed of the disk? A billiard ball at rest is struck (bold arrow in Fig. 8.53) by a cue with an average force of 5.50 N lasting for 0.050 s. The cue contacts the ball’s surface so that the lever arm is half the radius of the ball, as shown. ...Modern bowling alleys have automatic ball returns. The ball is lifted to a height of 2.00 m at the end of the alley and, starting from rest, rolls down a ramp. It continues to roll horizontally and eventually rolls up a ramp ...
