(II) A rotating merry-go-round makes one complete revolution in 4.0 s (Fig. 8-41).(,?) What the linear speed of a child seated 1.2 m from the center? (6) What is her acceleration (giv< components)?
Step 1 of 2</p>
(A) Time taken for 1 revolution (T) = 4 s.
Therefore, angular velocity of merry go round:
Thus, linear speed of the child:
