formula and solutions for 2 problems

1.)

If a spring (k=1000n/m)is compressed .80m and it is released launching a 4.0 kg block across the floor, how fast will the block be traveling when it leaves the spring? ignore friction and air resistance

2.)

If the coefficient of friction between the floor and block is .45, how far will the block slide?
