The amino acids are provided in 10 mg/mL amounts. Complete dilution calculations to determine how to create a range of five concentrations between 0-2 mg/mL and record them in the lab notebook. To do this, pick five amino acid concentrations (within the range) and calculate how many mL of the 10 mg/mL amino acid solution is needed in order to make your chosen concentrations if the total volume of your solutions is 5 mL Required:
How many mL of water will you need to add to each of the dilutions?

(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
