Moderate -0.5 This is a standard SUVAT kinematics problem involving a velocity-time graph with constant acceleration phases. Students need to find acceleration from the graph, calculate distance using area under the curve, and apply basic kinematic equations. These are routine M1 skills with straightforward multi-part structure, making it slightly easier than average but still requiring proper method application.

\(A\) and \(B\) are fixed points of a vertical wall with \(A\) vertically above \(B\). A particle \(P\) of mass 0.7 kg is attached to \(A\) by a light inextensible string of length \(3 \mathrm {~m} . P\) is also attached to \(B\) by a light inextensible string of length \(2.5 \mathrm {~m} . P\) is maintained in equilibrium at a distance of 2.4 m from the wall by a horizontal force of magnitude 10 N acting on \(P\) (see diagram). Both strings are taut, and the 10 N force acts in the plane \(A P B\) which is perpendicular to the wall. Find the tensions in the strings. [6]
