A solid, uniform disk of radius 0.250 meter and mass 48.7 kilogram rolls down a ramp of length 4.00 meter that makes an angle of 16.0 degree with the horizontal. The disk starts from rest from the top of the ramp.
(a) Evaluate the speed of the disk's center of mass when it reaches the bottom of the ramp.
m/s
(b) Obtain the angular speed of the disk at the bottom of the ramp.
rad/s
