Question

ChildTop ViewThe diagram above shows a top view of a child of mass 2x on a circular platform of mass 4x that is rotatingcounterclockwise. The platform does not experience friction.5. The child lets go of the platform and is released from uniform circular motion. Select the statement thatcorrectly describes the motion of the child.A. The child is now experiencing unbalanced forces and begins to accelerate proportional to the net forceas explained by Newton's Second Law of Motion.B. The child experiences no change to their motion because angular momentum cannot be createdor destroyedC. The child is no longer experiencing unbalanced forces and travels in a straight line path according toNewton's First Law of Motion.D. The child continues to travel along a circular path due to having experienced a centripetal force.

Answer 1

Centripetal Force:

Centripetal force can be defined as the amount of force acting on a body when it performs circular motion over a distance from the rotational axis. This force tends to throw the body tangentially in the direction of the motion of the body.

The correct statement that describes the motion of the child is (D)

The child continues to travel along a circular path due to having experienced a centripetal force.
