A 2.0 kg object compresses a spring with a spring constant of 100 N/m by a distance of 8 cm, and then the object is released. Assuming that the object maintains the same acceleration while the spring returns to equilibrium, how fast is the object moving after 1.2 s?

An object, whose mass is 0.480 kg, is attached to a spring with a force constant of 110 N/m. The object rests upon a frictionless, horizontal surface The object is pulled to the right a distance A = 0.120 m from its equilibrium position (the vertical dashed line) and held motionless. The object is then released from rest At that very instant, what is the magnitude of the object's acceleration (in m/s2)? m/s2

You have an oscillating spring with a spring constant of k=0.69 N/m. The mass on the end of the spring is m=0.34 kg. You may assume the spring is massless. Draw the displacement vs time, velocity vs time, and acceleration vs time graph for the this oscillating spring.
