A solid sphere (I = mr?) starts
from rest at a height h and rolls down an
incline of angle 0 without slipping. What
is the linear speed v of the solid sphere
once it reaches the bottom of the
incline?
Hint 1: If no slipping occurs, then the
angular speed of the solid sphere and its
linear speed are related by v
= wr
Hint 2: It is moving linearly (translating)
and rotating!
