Two points in the xy plane have Cartesian coordinates (1.50, -7.50) m and (-3.50, 3.50) m. (a) Determine the distance between these points. 12.1 m (b) Determine their polar coordinates. r= 7.6 0 = -78.7 (1.50, -7.50) (1.50, -7.50) (-3.50, 3.50) r = 4.9 (-3.50, 3.50) 0 = 45 X E counterclockwise from the +x-axis m o counterclockwise from the +x-axis
