. A mass of 400 g is attached to the spring and stretched a distance of 25.0 cm
from equilibrium. The mass is then released.
. At a position of 10.0 cm from the equilibrium the acceleration of the mass was
measured to be only77.00 m/s?, a good bit less than what was expected.
The students deduced that the surface the mass is sliding over must be producing
friction.
Use the information outlined above to determine the coefficient of kinetic friction, H.
