[问答题]
A solid sphere of mas)oug)t7 .bs )fcdq;cks 1.5 kg and radius 15 cm rolls x1z-3pqpb1u4oc2bwdk csd9/without slipping down a 35e incline that is 7.0 m long. Assume it started from rest. The moment of inertia of a sphere is gud4cwbkbc1/zo93 q 1pp d -2xsiven by $I = (2/5)MR^2$.
(a) Calculate the linear speed of the sphere when it reaches the bottom of the incline.
(b) Determine the angular speed of the sphere at the bottom of the incline.
(c) Does the linear speed depend on the radius or mass of the sphere? Does the angular speed depend on the radius or mass of the sphere?
参考答案:
(a) 7.5 m/s
(b) 50 rad/s
(c) The linear speed depends on neither the radius or the mass of the sphere. The angular speed depends on the radius of the sphere.
