Consider a line of children.
While the line of children is rotating, which of the following statements are correct? Check all that apply.

a) The player at the front of the line has the smallest angular acceleration.
b) The player at the front of the line has the smallest linear velocity.
c) All the children have the same angular acceleration.
d) All the children have the same linear velocity.

b,c

Explanation:

Velocity refers to the rate of change of position with respect to time and acceleration refers to the rate of change of velocity with respect to time. Both velocity and acceleration are vector quantities

While the line of children is rotating, the player at the front of the line has the smallest linear velocity and all the children have the same angular acceleration.

it is called kinetic energy
