edge of the track as shown. Which of the following statements is correct about the scenario? Select two answers.

If the block is released from a height $2h_1,$ the block will land at a distance $2D$ away from the end of the track.

If the block's mass is increased to $2M,$ the block will land at a distance $2D$ away from the edge of the track.

The total mechanical energy of the system containing only the block increases from the moment of release to the moment it strikes the ground.

The total mechanical energy of the block$-$Earth system remains constant.
