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?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
