A solid sphere of mass 1.5 kg and rv dwbg e-+j2dw+;mm;eb s-:sladius 1nums hq3y n 87+7aa0to5 cm rolls without slipping down a 35e incline that is 7.0 m long. Assume it started from rest. The momennom sa73ha 8qy07+tun t of inertia of a sphere is given 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.
