I'm betting this is the problem to which you're referring...

A 1.00-kilogram mass was dropped from rest from a height of 25.0 meters above Earth’s surface. The speed of the mass was determined at 5.0-meter intervals and recorded in the data table below.

In this case, reading the velocity off the graph directly, I would estimate the speed of the mass as approximately 15.5 m/s (which Castle Learning should accept...) Unfortunately, it apparently only accepts 15.7 m/s as its exact answer. Your responses were 15 m/s and 15.5 m/s.

As I can't adjust the assignment once it's been passed out, I will increase everyone's scores by 1 point on the assignment. Well done, and thanks for bringing this issue to light!
