1-5. In an experiment to determine the spring constant of an elastic cord of length
0.60 m, a student hangs the cord from a rod as represented above and then
attaches a variety of weights to the cord. For each weight, the student allows the
weight to hang in equilibrium and then measures the entire length of the cord.
The data are recorded in the table below:
Weight (N) 0 10 15 20 25
Length (m) 0.60 0.97 1.24 1.37 1.64

The student now attaches an object of unknown mass m to the cord and holds the
object adjacent to the point at which the top of the cord is tied to the rod, as shown.
When the object is released from rest, it falls 1.5 m before stopping and turning
around. Assume that air resistance is negligible.
3. Calculate the value of the unknown mass m of the object.
