What topic is this A level mechanics maths question from?

Hi I was doing this question and I found it bit tricky but I've got it now! I was wondering if anyone knew what topic it's from so that i can practice more of these questions :smile: It's from the 2022 Maths Edexcel Mechanics paper!

3. [In this question, i and j are horizontal unit vectors.]
A particle P of mass 4 kg is at rest at the point A on a smooth horizontal plane.
At time t = 0, two forces, F1 = (4i j)N and F2 = (λi + μj)N, where λ and μ are
constants, are applied to P
Given that P moves in the direction of the vector (3i + j)
(a) show that
λ + 7 = 0
(4)
At time t = 4 seconds, P passes through the point B.
Given that λ = 2
(b) find the length of AB.
(5)
I would say Kinematics, but with a bit of vectors as well.
Here's a decent sheet from Physics and Maths Tutor with answers at the end:
