A 2.50 kg mass is pushed against a horizontal spring of force constant 25.0 N/cm on a table with a coefficient of friction of 0.15. The spring is attached to the tabletop, but the mass is not attached to the spring in any way. When the spring has been compressed enough to store 11.5 J of potential energy in it, the mass is suddenly released from rest. a) Find the maximum speed of the mass. When does this occur? b) What is the greatest acceleration of the mass? When does it occur?

Question
A 2.50 kg mass is pushed against a horizontal spring of force constant 25.0 N/cm on a table with a coefficient of friction of 0.15. The spring is attached to the tabletop, but the mass is not attached to the spring in any way. When the spring has been compressed enough to store 11.5 J of potential energy in it, the mass is suddenly released from rest.
a) Find the maximum speed of the mass. When does this occur?
b) What is the greatest acceleration of the mass? When does it occur?
