1. D(X,Y) = D(1130,-950)m.

tanA = Y/X = -950/1130 = -8407,
A = -40.05 Deg, CW = -40.05 + 360 = 320
Deg, CCW.

D = X/cosA = 1130 / cos320 = 1475m @
320 deg = Displacement.

t = 22min * 60s/min = 1320s.

V = D/t = 1475m @ 320deg / 1320s =
1.12m/s @ 320deg.

V(h) = 1.12cos320 = 0.856m/s = hor comp. of Velocity.

V(v) = 1.12sin320 = -0.720m/s = ver
comp of Velocity.

V(X,Y),
V(0.856,-0.720).
