I spend alot of time studying after school and weekends. I spend much much more time studying then other people i could say but my results don't really show this. I sometimes finish studying and think to myself what new stuff i have learnt and i couldn;t answer myself.. I feel i have wasted so...
Ok thanks hope it works out good. I am just scared of my deputy principal who is in charge of changing the subjects. Hope he doesnt ask me why i have to change so late/
hmm thanks but would you know of a valid reason? I am thinking of picking English Extension because i am thinking of dropping from 3 unit to 2 unit maths.
I want to ask if it is still possible to add english extension now? Im in advance eng atm.
Also in Extension is the assessment based on hand in essays etc or are there any in class exams?
1) A rocket travelling at 5.50 x 10^1 fired giving a thrust of 1.880 x 10^3N. At the end of 6.2secs its velocity was 6.378 x 10^2. What was the average mass of the rocket?
2) The force applied by the fan to a glider of mass 850g was 0.34N. How long did it take for the glider to travel 80cm...
A car of mass 50KG accelerated from rest to 45ms-1 in 5secs. What net force must have been applied to produce this acceleration??
can u show me the working out and formula please^^
