A2.0 kg block is held at rest against a spring with a force constant k = 395 n/m. the spring is compressed a certain distance and then the block is released. when the block is released, it slides across a surface that has no friction except for a 10.0 cm section that has a coefficient of friction μk = 0.54. find the distance in centimeters the spring was compressed such that the block's speed after crossing the rough area is 2.5 m/s.
