A 1272.0 g mass is on a horizontal surface with uk and is in contact with a massless spring with a onstant of 727.0 N/m which is compressed. When ing is released, it does 5.23 J of work on the mass eturning to its equilibrium position. Calculate the e the spring was compressed. What is the velocity of the mass as it loses with the spring?

Please Asap 

part 1 - A 1272.0 g mass is on a horizontal surface with uk
= 0.50, and is in contact with a massless spring with a
force constant of 727.0 N/m which is compressed. When
the spring is released, it does 5.23 J of work on the mass
while returning to its equilibrium position. Calculate the
distance the spring was compressed.
part 2 - What is the velocity of the mass as it loses
contact with the spring?
