1.

Given a hooke's law spring, rod and stand, meterstick and set of known weights, what data must be taken in order to obtain the spring stiffness constant.
How will this data be used to find the spring stiffness constant?

2.

Given the setup indicated, what data is necessary to enable one to determine the initial speed required to cause the spring to go into the box?

3.

When the energy equation used to obtain the distance (x) the spring must be stretched in the above diagram in order to achieve the desired initial velocity (v) is solved for x, the value of x equals:
