Explanation / Answer

vector A = 2.8*cos(60) i + 2.8*sin(60) j = 1.4 i + 2.43 j

Vector B = 1.9*cos(60) i - 1.9*sin(60) j = 0.95 i - 1.65 j

A X B = (-1.4*1.65)k - (2.43*0.95) k = -2.31-2.31 = -4.62 k

so the answer is 4.62 cm^2

B) direction is along -Z-direction

C) B X A =( 0.95 i - 1.65 j ) X (1.4 i + 2.43 j)

B X A = (0.95*2.43) k + (1.65*1.4) k 4.62 k

D) direction is along +Z-direction
