B) if the actual counterweight fitted to this boom was
2350n:
i) what additional downward force must be applied
by the car park attendant to lift the boom
ii) what will be the normal reaction, n, at the end
support when the boom is resting on it?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
