Example Question WRITE ME DOWN •At noon, William Turner observes two ships, the black pearl –ship A, with position vector (-4i +3j)km and constant velocity of (4i + 17j)kmh-1 and the interceptor –ship B, with position vector (4i + 9j)km, travelling at a constant velocity of (-12i + 5j)kmh-1. At what angle to the stream direction must the boat move to minimize drifting? How far east did you walk? The bearing to a point is the angle measured in a clockwise direction from the north line. Two cars start from the opposite places of a main road, 150 km apart. Using the Pythagorean Theorem, the distance east is R2! Metro Rail is likely to be completed around 2020. A car is driven east for a distance of 88 km, then north for 28 km, then in a direction 30 degrees east of north for 25 km. Momentum = (mass-1)x(v1_initial northward) + (mass-2)x(v2_initial northward) Momentum = (1500-kg)x(0 km/h) + (3000-kg)x(-60.0 km/h) = -180,000 kg km /h.
