They have resolved the subsequent velocity into the components parallel and perpendicular to the original velocity

Then they have found the Impulse in those 2 directions

Then used Pythagoras to find the magnitude of the Impulse

Thanks, I saw that but don't fully understand the working out. For example in the first part, where did the -20 come from?

4. Wow. That paper looks evil. I'm struggling with M2 too but we are doing MEI not Edexcel. MEI is starting to look so much easier now...

It's difficult but do-able. FP3 is the real killer
