Re: 2009 HSC Physics Exam Question 19b

The sample answers (here: http://www.boardofstudies.nsw.edu.au/hsc_exams/hsc2009exams/pdf_doc/physics-sample-answers-09.pdf ) say at the start that the sample answers are not intended to be "even complete answers or responses", unfortunately. Regardless, your original answer is the right ...

Re: 2009 HSC Physics Exam Question 19b

No, the sample answers didn't multiply by 2. I have copy pasted from the sample answers: Will need the perpendicular component of the velocity as the acceleration influences this component of the velocity only vh = 6.0 × 106 sin 60° = 5.196 × 106 m s−1 Determine time using v = u + at 0 = 5.196 × 106...

CONTINUED I then calculated the vertical velocity of the electron, given by 6.0 x 10^6 x sin60 = 5.196 x 10^6 ms-1 up the page, which was the same as the sample answer. Here, the question asks us to calculate when the electron reaches D. I used the equation y = ut + 1/2 at^2 I set y=0, since the ver...
