Question

Chapter 10 1) Two children are ridi rotation than child B. Which child has the larger angular speed? A) Child A B) Child B ng on a merry-go-round. Child A is at a greater distance from the axis of C) They have the same zero angular speed D) They have the same non-zero angular speed. E) There is not enough information given to answer the question 2) Two children are riding on a merry-go-round. Child A is at a greater distance from the axis of rotation than child B. Which child has the larger tangential speed? A) Child A B) Child B C) They have the same zero tangential speed. D) They have the same non-zero tangential speed E) There is not enough information given to answer the question.

Explanation / Answer

1) angular speed W = V/r

case1) if V same then child B has larger angular speed . OPTION (B)

case2) if V is not same then we can't say anything. OPTION (E)

2) tangential speed V = W*r

case1) if W is same then child A has larger speed . OPTION(A)

case2) if W is not same then we can't say anything. OPTION (E)
