Asolid block of mass m2 = 0.88 kg, at rest on a horizontal frictionless surface, is connected to a relaxed spring (with spring constant k = 146 n/m whose other end is fixed. another solid block of mass m1 = 1.25 kg and speed v1 = 2.40 m/s collides with the 0.88 kg block. if the blocks stick together, what is their speed immediately after the collision?

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
