Q1. A submarine dives 90.0 m at an angle of 12.0° below the horizontal. What are the horizontal and vertical components of the submarine's displacement? (Assume that upward and the direction of the submarine's horizontal motion is positive.)

Q2. A ferry boat transports tourists among three islands. It sails from the first island to the second island, 4.7 km away, in a direction 37.0° north of east. It then sails from the second island to the third island in a direction 69.0° west of north. At last it returns to the first island, sailing in a direction 28.0° east of south. Compute the distance between

(a) second and third islands

(b) first and third islands
