I was able to do part B but I cant get A and C.

PART A.

Find the xx- and yy-components of the vector d⃗ d→ = (8.0 kmkm , 23 ∘∘ left of +y+y-axis).

PART C.

Find the xx- and yy-components of the vector a⃗ a→ = (10 m/s2m/s2 , 37 ∘∘ left of −y−y-axis).

Answer #1

Here we have given that,

Part A

d = 8 km , 23° left of y axis

So

X component of d will be given as,

Xd = 8 sin23 ° = 3.125 (-i) km

Y component of d will be given as,

Yd = 8 cos 23° = 7.3640 (+j) km

Part C

Now for the vector a we have,

a = 10 km , 37° left of -y axis

So that,

X component of a will be

Xa = 10 sin37° = 6.0181(-i) km

Y component of a will be,

Ya = 10cos37° = 7.98635 (-j) km
