A uniform solid disk of mass 3.60 kg and diameter 45.0 cm starts from rest and rolls without slipping down a 39.0 ? incline that is 6.25 m long.  g = 9.81 m/s2 .

(a) Calculate the linear speed of the center of the disk when it reaches the bottom of the incline.

b) Determine the angular speed of the disk about its center at the bottom of the incline.

c) Through what angle (in radians) does this disk turn as it rolls down the incline?

d) Does the linear speed in (a) depend on the radius or mass of the disk?

1. The linear speed depends on the radius of the disk.

2.The linear speed depends on the mass of the disk.

3.The linear speed depends neither on the radius nor on the mass of the disk.

4.The linear speed depends both on the radius and the mass of the disk.
