Aforce
f acts in the x - direction, its magnitude given by f = ax^2, where x is in meters and a =5.0n/m^2
. find the work done by this force as it acts on a particle moving from x = 0 to x = 6.0 m.

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?
