A spring of spring constant k=12.5N/m is hung vertically. A .500kg mass is then suspended from the spring. What is the displacement of the end of the spring due to the weight of the .500kg mass?

Answer #1
since weight = restoring force
hence mg = k x
or displacement x = mg/k
hence x = (0.5*9.8)/12.5
hence x = 0.392 m

    A spring stretches 0.150 m when a 0.300 kg. mass is hung vertically from it. From this information you can determine the spring constant, k. Next, the spring is set up horizontally with the 0.300 kg. mass resting on a frictionless table. The block is pushed so that the spring is compressed 0.100 m from the equilibrium point, and released from rest. Determine: The spring constant k (in N/m)? The amplitude of the horizontal oscillation (in m)? The angular frequency,...

    A spring with spring constant k is suspended from the ceiling. A block of mass M hangs from the spring. A bullet of mass m is fired vertically upward into the bottom of the block, get embedded in it, and the spring's maximum compression d is measured. The block and bullet system then oscillates. Find an expression for the bullet's speed vB in terms of m,    M, k and d.     Find the frequency ? of the oscillation. Find the...

    A spring is hung vertically from a fixed support. When an object of mass m is attached to the end of the spring, it stretches by a distance y. When an object of mass of 2m is hung from the spring, it stretches by a distance 2y. A second, identical spring is then attached to the free end of the first spring. If the object of mass 2m is attached to the bottom of the second spring, how far will...
