Classify each material as an alloy or ceramic

alloy- Bronze,brass, steel and glass

Ceramic- brick  and tile

Explanation

Alloy  is a metal  made up  by combining  two or  more  metallic elements.  

for example, bronze  is made up  by alloying tin with copper.

Ceramic  materials  is an inorganic,non  metallic which is often crystalline oxide,nitride  or carbide  material.

For example, Tiles are made up of natural clay sand and water.

(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
