Explanation / Answer

r = (26 x 3 x 60)(-j) + (25 x 2.80 x 60)(-i) + (30 x 1 x 60)(-cos45i + sin45j)

(A)

r = -4680j - 4200i - 1272.8i + 1272.8j

r = - 5472.8i - 3407.2j

magnitude = sqrt(5472.8^2 + 3407.2^2) = 6447 m

direction angle = tan^-1(3407.2/5472.8) = 32 deg

(C) average velocity = r / t

v = - 13.4 i - 8.35j

magnitude = sqrt(13.4^2 + 8.35^2) = 15.8 m/s

direction = 32 deg
