Question 1 A particle falls freely under gravity from rest at a point . After it has fallen for one second another particle is projected vertically downwards from with speed m/s. By considering the relative motion of the particles, or otherwise, find the time and distance from at which they collide. Show the motion of... Read More

What Does “This is a hard course” Really Mean.
I have given many grinds to third level students over the years and there is a particular warning given to students in certain courses, that is, “This is a hard course”. Now, I do not doubt that that may be true but I have observed some interesting data around when this is said. Namely: This... Read More

Question 1 A racing car covers a journey of km from rest to rest. It accelerates uniformly in the first minute to reach its maximum speed of m/s, it holds this speed for a certain time and then slows uniformly to rest with a retardation of magnitude three times that of the acceleration. i) Draw...

Project Maths: Hacking our way to a better PISA placing
I’ll put my cards on the table from the start, I’m not a fan of the Project Maths Syllabus (the new Mathematics Syllabus in Ireland). There have been many voices discussing the advantages and disadvantages of the new Syllabus. And I don’t intend to add my voice to that chorus as what I have to... Read More

Question 1 State the principle of the conservation of momentum. A car weighing tons and moving at m.p.h. along a main road collides with a lorry of weight tons which emerges at m.p.h. from a crossroad at right angles to the main road. If the two vehicles lock, what will be their velocity after the... Read More

General Derivative Test Flow Chart
I was teaching my students today how one could use higher derivates to determine the shape of a curve at a particular point. The problem that really can be confusing is the case when I felt that a flow chart with pictures would be the best way to represent the process for deciding... Read More
