Given the vectors A = 2.00i + 6.00j and B = 3.00i 2.00j, (a) draw the vector sum C = A + B and the vector difference D = A - B. (b) Calculate C and D, first in terms of unit vectors and then in terms of polar coordi- nates, with angles measured with respect to the + x axis. A ferry boat transports tourists among three islands. It sails from the first island to the second island, 4.76 km away, in a direction 37.0 north of east. It then sails from the sec- ond island to the third island in a direction 69.0 west of north. Finally it returns to the first island, sailing in a di- rection 28.0 east of south. Calculate the distance between (a) the second and third islands (b) the first and third islands
