That's true, you can't get any more precise than what's measured to the least precision.
Answer:
C. hyperbola
Explanation:
From Boyle's law:
PV = k, where k is a constant
Solving for P:
P = k / V
At first glance, this equation doesn't fit any of the options. But when you graph it, you can see that it's actually a <em>rotated</em> hyperbola.

The position of the mass is given by (in cm):

The velocity is the derivative of the position:

Substituting t=0.40 s, we can find the velocity at this time:
