A ramp is inclined at an angle of 31° with the horizontal. You release a thin spherical shell of radius 0.30 m and it rolls without slipping, down the ramp for a distance L. If the mass of the shell is 1.5 kg, and its angular speed when it reaches the end of the ramp is 28.8 rad/s, what is the value of L, in meters?
