1) Two points in the xy plane have Cartesian coordinates (1.00, -4.00) m and (-5.00, 5.00) m. Determine their polar coordinates @ (-5.00, 5.00) r = ? θ = ? 2) A plane flies from base camp to Lake A, 290 km away in the direction 20.0° north of east. After dropping off supplies it flies to Lake B, which is 230 km 30.0° west of north from Lake A. Graphically determine the distance and direction from Lake B to the base camp. Distance = ? Direction = ? 3) Given the vectors = 5.00 + 8.00 and = 3.00 - 2.00. vector D r = θ = I have absolutely no clue how to solve these, or where to begin. I don't have my book yet since it has not been delivered, and I don't mean to be a pest, but I really need help. Thank you!
