a) Calculate the linear and rotational speed of a solid sphere of radius 20.0 cm and mass 1.20 kg that is released from rest and rolls down a 30.0 degree incline that is 10.0 m long, when it reaches the bottom.
b) Calculate the ratio of rotational kinetic energy to translational kinetic energy.
c) Does your answer to b.) depend on the sphere's radius or mass? Please answer all sections and explain.
