7) An ideal spring with a spring constant of 1375 N/m sits horizontally on a steel floor with one end attached to a rigid wall. A 5.00-kg plastic block is placed on the floor and used to compress a spring by 0.200 meters. The block is released from rest so that the spring pushes it horizontally across the floor. The coefficient of kinetic friction is uk = 0.600 between the plastic block and the steel floor. How many seconds after it loses contact with the spring does the block come to a complete stop? . Hint: this needs to be solved as a two-stage problem, and note that there is friction both before and after the block loses contact with the spring. You may use g≈ 10.0 m/s² for ease of calculation. 0-200 7) An ideal spring with a spring constant of 1375 N/m sits horizontally on a steel floor with one end attached to a rigid wall.
