Re: HSC 2012 Marathon :) I had a feeling you wanted it this way when I saw your working. You should said it like this: A point mass is projected from the origin O with velocity of 20m/s at an angle of 45 degrees to the horizontal. Find the time at which the velocity of the mass is at an angle...

Re: HSC 2012 Marathon :) yeh dude doesn't sound like you worded the question right.

Re: HSC 2012 Marathon :) But I now get 2.07 seconds..

Re: HSC 2012 Marathon :) lol I just looked at my working again after you said that and I saw my time in terms of g: t=[20sqrt(2)/g][1-tan(15)] and when I substituted g=10 I put 10sqrt(2)[1-tan(15)] for some retarded reason lol.

Re: HSC 2012 Marathon :) I got 10.35 seconds.

OMGGGGGGZZZZZZZZZZZZZZZZZZZZZZZZ My mind told me that there were 3 digits for some reason.. Alright thanks guys.

yeh this is correct.
