The block is pulled 0.15m below its equilibrium position and released from rest.

(b) Determine the maximum displacement of the mass from equilibrium.

(c) Calculate the elastic potential energy of spring just as the block is being released.

(d) Calculate the maximum speed the block will have during its motion.

(e) Calculate the displacement of the block from equilibrium when the kinetic energy of the block is equal to the elastic potential energy of the spring.

The block is brought to rest at equilibrium. The block is then pulled down half the original distance.

(f) Will the new period for the motion of the block be greater than, less than, or equal to the original period for the motion of the block?

____ Greater than ____ Less than ____ Equal to
