Could somebody help walk me through this problem?:

A spring has its right end fixed and is installed on a horizontal table so that the free end, in equilibrium, is at x= 3m. A 1.65 kg block coming from the left slides along the table. When it passes the origin, it is moving at 5.58 m/s. It strikes the spring, compresses it momentarily, and is then sent back toward the left, where it eventually comes to rest at the point x= 1.5m. The coefficient of kinetic friction betweeen the block and the table is .300. By what distance was the spring compressed?

2. Relevant equations

F(of kinetiic friction)=(coefficeint of kinetic friction)(m)(g)

KE=.5(mass)(velocity squared)

3. The attempt at a solution

KE=.5(1.65kg)(5.58 m/s squared)

=25.57Joules

F(of kinetic friction)=.3(1.65)(9.8)

=4.851 N
