Question 6 - A-Level Maths

Show that, when \(P\) is in equilibrium, \(O P = 7.25 \mathrm {~m}\).
Verify that \(P\) and \(Q\) together just reach the safety net.
At the lowest point of their motion \(P\) releases \(Q\). Prove that \(P\) subsequently just reaches \(O\).
State two additional modelling assumptions made when answering this question.
