=> The player at the front of the line has the smallest linear velocity.

All the children have the same angular acceleration.

B) Now consider the children’s linear accelerations. Which of the following statements are correct?

=> The last child in the line has the greatest tangential acceleration.

The last child in the line has the greatest radial acceleration.
