A particle moves on a line so that its distance from the origin at time t s is x m and its velocity is v m/s. i) The acceleration satisfies (d^2 x)/(dt^2) = n^2 (3 – x) where n is a constant, and the particle is released from rest at x = 0. a) Show that ½ v^2 – n^2 (3x – ½ x^2) = 0 b)...

What is the structure of reports in in-class assessments. I've seen beautiful structures on this website, with abstracts et cetera but I'm looking for the proper and efficient structure in an assessment where you do the experiment on the day. Thanks.

Answers say 32.2 min. ln(5)/5 = 0.322 (3d.p.). Why do we need to multiply by 100?

Ex25(e) page 129 Q4. old New Senior Mathematics 3UNIT A body, initially at room temperature 20°C, is heated so that its temperature would rise by 5°C/min if no cooling took place. Cooling does occur in accordance with Newton's Law of Cooling and the maximum temperature the body could attain is...

Ex 24(c) Q17. pg. 79 New Senior Mathematics 3UNIT Fitzpatrick 17. Through the vertex A of a parabola, chords AP and AQ are drawn at right angles to one another. Show that for all positions of P, PQ cuts the axis of the parabola in a fixed point K. Thanks

Could I borrow those MedEntry past papers. I am in a similar situation like you, but my family friends aren't doctors so all I got are maths extension 1 past papers lol not MedEntry ones.
