A ball m = 1.0 kg is dropped from a balcony A at 8.0 m above the ground. The ball is caught at point B at 4.00 m above the ground. Take the reference point of the zero gravitational potential energy configuration at the ground, such that Ug = 0 at y = 0. Take g = 9,8 m/s2. Calculate the work done by the conservative force Wg between A and B.

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?
