Asolid, uniform disk of radius 0.250 m and mass 44.9 kg rolls down a ramp of length 3.80 m that makes an angle of 16° 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 4.153x your response differs from the correct answer by more than 10%. double check your calculations. m/s (b) find the angular speed of the disk at the bottom of the ramp. 16.61 your response differs from the correct answer by more than 10%. double check your calculations. rad/s
