A cylinder of radius 2.59 cm and a sphere of radius 8.72 cm are rolling without slipping along the same floor. The two objects have the same mass. If they are to have the same total kinetic energy, what should the ratio of the cylinder's angular speed ?cyl to the sphere's angular speed ?sph be?

What angle did the tires rotate through? b. If the vehicle traveled at an average velocity of 15.0m/s, what was the average angular velocity of a point on the tire's edge? c. What was the average centripetal acceleration that a point on the edge of one of those tires experienced during that time?

A hollow ball has a radius of 2.47cm and a mass of 7kg and is rolling, it is traveling with a translational speed of 8m/s.  What is its kinetic energy?

A stick with a mass of 0.164 kg and a length of 1.00 mis pivoted about one end so it can rotate without friction about a horizontal axis. The meter stick is held in a horizontal position and released.    Part AAs it swings through the vertical, calculatethe change in gravitational potential energy that has occurred.Use 9.81 m/s2for the acceleration due to gravity. Part BAs it swings through the vertical, calculate the angular speed of the stick.    Part CAs it swings through the vertical, calculate the linear speed of the end of the stick opposite the axis.     Part DFind the ratio of the speed of a particle that has fallen a distance of 1.00 m, starting from rest, to the speed from part (C).
