**1. The problem statement, all variables and given/known data**

The figure below shows the x(t) curves for three experiments involving a particular spring-box system oscillating in SHM.

(a) Rank the curves according to the system's angular frequency, greatest first (use only the symbols > or =, for example 1>2=3).

(b) Rank the curves according to the spring's potential energy at t = 0, greatest first.

(c) Rank the curves according to the box's kinetic energy at t = 0, greatest first.

(d) Rank the curves according to the box's speed at t = 0, greatest first.

(e) Rank the curves according to the box's maximum kinetic energy, greatest first.

**2. The attempt at a solution**

Clueless, do I have to use the formulas or something to find out which ones are greater?
