A mass is attached to a vertical ideal spring lie, the spring is assumed to be massless and obey's Hooke's law) and comes to rest at its equilibrium position. The mass is then pulled down and released, setting it into simple harmonic motion. You may ignore air resistance in your analysis of the system. - For each of the following scenarios. in which direction is the requested force acting on the oscillating mass? State your answer as either "+" (for upwards), "" [for downwards), or "O" to indicate the magnitude of the force is zero. After giving your answer, provide an explanation as to the physical explanation for your choice. 1. In which direction is the force on the mass due to the spring when the mass is passing upwards (while oscillating) through the equilibrium position of the mass-spring system. State the direction l"+", "7", or "0") and provide your explanation. 2. In which direction is the net force on the mass when the mass is passing downwards (while oscillating) through the equilibrium position of the mass-spring system. State the direction ("+", "r", or "0") and provide your explanation. 3. In which direction is the force on the mass due to the spring when the mass is momentarily at rest at the bottom of its oscillation. State the direction l"+", "", or "0") and provide your explanation. 4. In which direction is the net force on the mass when the mass is momentarily at rest at the top of its oscillation. State the direction I"+", "", or "0") and provide your explanation. 5. Before the mass is set into simple harmonic motion, in which direction is the force on the mass due to the spring when it is at rest at the equilibrium position of the mass-spring system. State the direction ("+", "". or "0") and provide your explanation
