A solid, uniform disk of radius 0.250 m and mass 61.8 kg rolls down a ramp of length 4.00 m that makes an angle of 12.0\deg with the horizontal. The disk starts from rest from the top of the ramp. (a) Find the speed of the disk's center of mass when it reaches the bottom of the ramp. Incorrect: Your answer is incorrect. Your response differs from the correct answer by more than 100%. m/s (b) Find the angular speed of the disk at the bottom of the ramp.
