Can anyone work out this difficult maths involving vectors?
2 replies, posted
So I'm really struggling with this, anyone want to try?
Q4) Find the position vector of B relative to A, IE find AB
A: AB = -A+B
Q4 completed
Q5) Use 4 to show d is the distance between the yachts at any time t then
d²=25t² - 214t + 458
Some useful stuff:
Yacht A location : [-10, 4]
Yacht B location : [3, -13]
Velocity vector yacht A : [2, -1]
Velocity vector yacht B : [-1, 3]
I need help with Question 5
