Problem: Calculate the total kinetic energy of a solid sphere with a mass of 4.0 kg that's rolling without slipping at a linear speed of 3.0 m/s. Be sure to include the rotational kinetic energy of the sphere in your calculation.
Please show the work for the calculation so I can understand what I'm doing. Thanks!
