How to make foam please answer me

Step 1

Brush foam latex mold release into the mold or baking sheet being used. The baking sheet is for flat sheets of foam rather than a specific shape, for which a mold is used.

Step 2

Allow the mold release to dry and buff off any excess buildup.

Step 3

Pour one-third of a pound of latex base into a mixing bowl, followed by 1 ounce of foaming agent and a half ounce of curing agent.

Step 4

Measure a half ounce of gelling agent in a separate cup.

Step 5

Mix the foam at the following speeds: one for 1 minute; then 10 for 4 minutes; then four for 1 minute; and finally one again for 4 minutes. These speeds and times are specifically for a KitchenAid mixer. For other brands, see the references.

Step 6

Slowly add the gelling agent after 10 minutes. Drizzle it in over the course of 30 seconds; do not dump it in.

Step 7

Allow the foam to mix for one more minute.

Step 8

Remove the bowl from the mixer and brush or pour the foam into the mold or baking sheet. Close the mold and strap it together if it has more than one piece.

Step 9

Put the mold or baking sheet in the oven when the foam has gelled. If you can poke the foam with your finger without it sticking to the foam, the foam has gelled.

Step 10

Bake the foam at 180 degrees F for 2 to 3 hours for small molds and baking sheets, 3 to 4 hours for large molds.

Explanation:

If this does not help look it up on google.

also did not know what type of foam this is foam rubber.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
