I said as the angle of projection increases, the range decreases. So basically I put what you put, not sure how that is 2 marks though?


you had to write that above 45 degrees the range started to decrease

Was 22.5 m/s the correct answer for the distance-time question. Also, what did people put for the multiple choice graph rocket question. I think I put B..


I put A

Damn it I put the pressure/force is transmitted through the liquid equally in all directions??

I think that will get the mark as well!

i got 17m/s as the distance was 170 and the time was 10 seconds
What did everyone put for the 'momentum is conserved' question?


I put the one that began as a curve and then levelled off...
i got 12 as well for the half life, but most people saying it's 4.5
36/2 =18/2 =9 /2 =4.5

The the momentum after an event is equal to the momentum before an event

I got that too

Conservation of momentum is when the momentum before an event and the momentum after an even are equal

Something along those lines

But it wanted the fastest speed, so I presume you had to take points from where the line was straight and then work it out from there...

Initial momentum = final momentum

Momentum before = momentum after

momentum is the same before and after the collision
Me too for the graph one; also what question do you mean by the conservation of momentum one? The one where you had to find the velocity of b?

I got confused because it said it fell from the sky onto the ground

Yeah you did, but 17 m/s is right

Anyone else get 18 turns for the number of turns?
