Consider hanging a block with mass m=1.0 kg from a spring with spring constant k=98 N/m.
a) How much is the spring stretched at the equilibrium position (the position where the block hangs without bouncing)?
b) If we lift the block up to the position where the spring is unstretched, and then let it go, what's the maximum speed of the block as it bounces? (neglect any friction)
c) At the lowest point of the block's bounces, how much further past the equilibrium position is the spring stretched?

A block of mass m = 4.5 kg is attached to a spring with spring constant k = 710 N/m. It is initially at rest on an inclined plane that is at an angle of θ = 25° with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is μk=0.18. In the initial position, where the spring is compressed by a distance of d = 0.12 m, the mass is at its lowest...

A spring of spring constant k=261 N/m is attached to a block of mass 1.38 kg and stretched horizontally to a position 15.0 cm from the springs equilibrium position. The spring and mass are released and oscillate in simple harmonic motion across a frictionless horizontal surface. What is the maximum speed obtained by the mass? m/s
In the figure below, a block of mass m = 2.0 kg slides head into a spring of spring constant k = 320 N/m. When the block stops, it has compressed the spring by 6.5 cm.
