Block 1 is at rest on a horizontal surface and is connected to a wall by an ideal spring. Friction between block 1 and the surface is negligible. Block 1 is held at rest at point A. released from point \( A \) and allowed to oscillate. Later, block 1 is momentarily at rest at point C. Consider the positive horizontal direction to be toward the right as shown in the figure above. (a) The dot below represents block 1 . i. On the dot below to the left, draw an arrow indicating the direction of the net force exerted on the block just after it has been released at point A. On the dot below to the right, draw an arrow indicating the direction of the net force exerted on the block when it has reached Point C. Any arrows draw should start on, and point away from, the dot. if

When block 1 is released from point A, the net force acting on it is directed to the right, toward the equilibrium position of the spring. Therefore, draw a rightward arrow starting on the left side of the block, indicating that the force exerted by the spring is pulling it in that direction. At point C, the block is momentarily at rest. Here, the spring force has acted on the block, and it should be drawn pointing leftward, since it’s trying to pull the block back towards the equilibrium position. So, draw a leftward arrow starting from the dot on the right, signaling this opposing force when at rest. Visualize it like this: at point A, it's like letting a slingshot go, and at point C, it's the spring's effort to return to the calmness of its resting state!
