RELATIVE MOTION QUESTIONS!!!!!!! Q1 100km/h-60km/h =40km/h west

Q2 i)0km/h ii)27.78km/h * 2 =55.56km/h

Q3 30.5m/s north-25m/s south =5.5m/s north

Q4 12m/s-5m/s =7m/s south

Q5 90/3.6 =25m/s 100/3.6 = 27.777... 25*10=250 27.777...*10 = 277.777... 277.777...+250 = 527.777... metres in 10 seconds 527.777...>500 therefore you cannot overtake the car safetly

Newtons Universal Law of gravitation

Is the universal gravitational constant times the mass of each object all divided by the square of the distance between two objects. It is represented by the formula Fg = G*M1*M2/r2 It is important because you can then find out the the gravitational pull...

Social Implications of collisions When there is a collision no matter what the vehicle usually compensation and damages has to be paid this is a financial implication. Also if people die this is very bad and then people are very sad and if people dont die they are injured then they have to go to hospital more financial implications and when families are effected there is severe emotional pain and this is a social implication because people have to take time off from work and stuff...

Our Egg Experiment: We provided a belt to a egg and some cushioning to his back hoping that the the belt would prevent it from kmoving out of the seat we developed and then the cotten wool would protect it as it went back from the impact......... However it FAILED and this is because it was not adequately restrained because we were only allowed to put one seat belt because miss would not let us put any more also she did not let us put a helmet on it so its skull got crushed and dismembered its lower section. I f i could change our saftey precausions i would add a helmet, 5 seatbelts make a cotton wool seat make some sort of coffin like contraption put the egg in it cover in cotton wool add another 5 seat belts then launch it into the sun
