A fish swimming in a horizontal plane has velocity vi = (4.00 i – 3.00 j) m / s at a point in the ocean, with a displacement of Indeed a rock ri = (10.0 i + 4.00 j) m. After the fish swims with constant acceleration for 15.0 s, its velocity is v = (16.0 i – 5.00 j) m / s. Q: What are the cmponents the ACC? What direction from vector ai?
(15 V (0) = (4, -3) v) = (16, (15 -5) dv = v) – V (0) = (12, -2) dt = 15 -0 = 15 = acceleration dv / dt = (12/15, -2/15) = (0.8, -0.1333) = 0.8 i – j 0.1333 is the tip acceleration towards below the i-direction, the angle arctan (0.1333/0.8) = 9.46 degrees
