    A spring with a spring constant of 718 N/m lies on a horizontal surface and that surface is y = 0 m to calculate the gravitational potential energy. A mass of 3 kg is compressed 0.45 meters into the spring and held still. After the mass is released it slides over a horizontal surface in which a 3.4 meter portion of the surface has friction with a coefficient of kinetic friction of 0.30. After the horizontal surface, it travels up...

    A 12-kg block is pressed against a spring (spring constant 620 N/mN/m ), compressing it some distance. The block is released from rest and slides across a track as shown in (Figure 1). While most of the track is frictionless, there is a 55-cm section of track that has a coefficient of friction with the block of 0.3. A bit further on, the track ascends into a hill that is 40-cm tall. Part A: What is the minimum compression of...
