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 \(t=5\).
The worked solutions to these exam-style questions are only available to those who have a Transum Subscription.
Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves.
This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures.
A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience.
