Problem 4: For vectors B =- î - 4ĵ and A = - 3î - 2ĵ.

I need help understanding how it’s x=14 at t=10 secs?

Show that for any scalar λ, the vectors x, y given by satisfy the equations X = 2 à + 9 (ªx ³)¸ ÿ – (¹ − p ³) ; _ P (ẵx ³² = (1 − x - (a b )₁ a _ p (a × b ) a² 2 9 a² px +qy = a and x × y = b.

(e) In situation (3), give the direction of a by naming either a quadrant or a direction along an axis.

ii) Evaluate the simplest SI unit of K, if K= m²x2

a particle moves along xy-plane with a position of x(t)=sin(2t)+3 cos (4t) y(t)=1/2 sin(t) - 6cos(3t)
