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?
