A block pushed against an ideal spring

A block of mass 4 kg is pushed against an ideal spring of force constant 1200 N/m compressing it 10 cm. When released from rest it slides 4 m until it stops along a rough horizontal surface. The work done by friction is?

"barrel is horizontal. JUST NEED HELP ON C AND D. I INCLUDED A AND B JUST IN CASE. a) Calculate the speed with which the ball leaves the barrel if you can ignore friction. 6.93m/s. b)Calculate the speed of the ball as it leaves the barrel if a constant resisting force of 6.00 {\rm N} acts on the ball as it moves along the barrel. 4.9m/s c) For the situation in part B, at what position along the barrel does the ball have the greatest speed? (In this case, the maximum speed does not occur at the end of the barrel.) d) What is that greatest speed?"
