Question

David places a rock in a sling and swings it around over his head clockwise. He faces his target – an old oak tree. To hit his target, he should stop pulling the sling inward when

A. the sling is to his right.
B.the sling is in front of him.
C.the sling is to his left.

Answer 1

To hit the target, David should release the sling when it's to his right, considering the principles of circular motion in physics. Angular momentum of a lever would be determined by mass, radius, and angular velocity.

Step-by-step explanation:

To hit his target, an old oak tree, David should release the sling when the sling is to his right. In the context of circular motion in a clockwise direction (as seen from above), this would be the point in the rotation when the rock in the sling is facing toward the intended target, accounting for the inertia of the rock which will continue to move in the tangential direction once released.

The descriptions provided in the question seem to relate to concepts of circular motion and forces, illustrating inertia, angular momentum, and the effect of frame of reference, all key concepts in physics.

When considering the measurements needed to determine angular momentum for a lever system, important factors would be the mass of the rock positioned on the lever (mass), the distance from the fulcrum to the rock (radius), and the angular velocity of the lever (angular velocity).
