To create a cement block mold for your DIY project, you can use materials like wood, plastic, or metal to construct a frame in the shape and size of the block you want to make. Make sure the frame is sturdy and has smooth surfaces to ensure the cement sets properly. Pour the cement mixture into the mold and allow it to cure before removing the mold to reveal your cement block.

The change in momentum of the cement block is 10 kg * 2 m/s = 20 kg m/s. The average force applied to stop the block is the change in momentum divided by the time taken, which is 20 kg m/s / 0.5 s = 40 N. Therefore, the average impact force on the pillow is 40 Newtons.
