World Population Graph (10 MARKS) 1. Using the information provided in the table, create a graph for world population,
2. Time will be on the x-axis, starting at 5000 BC going to 2000 AD as shown
below:
5000 4000 3000
2000 1000
1 1000
2000
3. On the y-axis you will have population in billions from 0 to 7,35. Use an
appropriate scale to fit all the data. Graph the points,

hi my dude or dudette

(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
