A recipe for Norwegian Apple Pie is given below. Ingredients: One egg, cup sugar, one tsp vanilla extract, one tsp baking powder, cup all-purpose flour, cup chopped walnuts, one cup diced apples

Directions: Beat egg, sugar, vanilla extract, and baking powder together until smooth. Beat in the flour until smooth and well blended. Stir in apples and walnuts. Put into a lightly greased nine inch pie pan. Bake for 30 minutes at 350 degrees. Pie will puff as it cooks and then collapses as it cools.

For each ingredient, identify as either a pure substance or a mixture and identify physical and/or chemical properties.

(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
