Exam-Style Question on Kinematics
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 56. This question is similar to one that appeared on an IB Standard paper in 2014. The use of a calculator is allowed.
Pob and Wie are travelling from Bangkok to Khon Kaen.
Pob travels at a velocity given by \(V_P=50-t^2\), where t is in seconds and the velocity is in ms-1.
Wie's displacement from Bangkok in metres is given by \(S_W=2t^2+70\).
When \(t=0\), both vehicles are at the same point.
Find Pob's displacement from Bangkok when \(t=5\).
