Exam-Style Question on Kinematics
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 598. This question is similar to one that appeared on an IB AA Standard paper in 2021. The use of a calculator is allowed.
A particle P moves along the x-axis. The velocity of P is \(v\)ms-l at time \(t\) seconds, where \(v(t) = 5 + 3t - 2t^2\) for \(0 \le t \le 3\). When \(t = 0\), P is at the origin O.
(a) Find the value of \(t\) when P reaches its maximum velocity.
(b) Find the distance of P from O at this time.
(c) Sketch a graph of \(v\) against \(t\), clearly showing any points of intersection with the axes.
(d) Find the total distance travelled by P.
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.
