Two blocks are initially at rest with a compressed spring between them. when the spring is released, the 2m block moves to the left and the m block moves to the right. this represents an inelastic collision in a closed system. what best describes the blocks after the spring is released? the total energy is zero. the total momentum is zero. the momentum of the m block is zero. the momentum of the 2m block is zero.

In an inelastic collision the kinetic energy is not conserved, but the total momentum of the system is conserved.

In other words; the Initial momentum is equal to the Final Momentum :

Then:

This means that after the collision the kinetic energy is transformed (dissipated) into another type of energy (caloric energy, for example); and there may be deformation in the blocks.

Therefore, the sentence that best describes this situation is:

v 154.9= 0.9 length length s little over 154.9cm

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
