A spring having k = 18 N/m is joined to a wall and a mass M = 2 kg oscillates on the horizontal surface with no friction. The mass is pulled back to the displacement of x = .2 m.
i) What force is required?
ii) Determine the magnitude of the acceleration of the block half-way back to equilibrium?
iii) Determine how much energy is stored in the system?
iv) The block is free. Determine its speed at the equilibrium position?
v) At what distance from equilibrium will its speed be half of the maximum speed?
vi) Determine how long did it take to return to the equilibrium position?
vii) When the mass were pulled back twice as far (similar spring and mass), which of the given values computed above WOULD CHANGE: force, maximum speed and time?
