A uniform solid sphere rolls down an incline.

Question

(a) What must be the incline angle if the linear acceleration of the center of the sphere is to have a magnitude of 0.20g?
1°
(b) If a frictionless block were to slide down the incline at that angle, would its acceleration magnitude be more, less than, or equal to 0.20g?

Answer 1

A)16.3 deg

B) The acceleration magnitude would be more than 0.20g
