The water from a fire hose follows a path described by y equals 4.0 plus 0.8 x minus 0.40 x squared (units are in meters). if v subscript x is constant at 5.0 m/s, find the resultant velocity at the point (2.0 comma 4.0 ). find the magnitude of the velocity of the water at the point (2.0 comma 4.0 ). the magnitude is approximately 6.4 m/s. (type an integer or decimal rounded to one decimal place as needed.) find the direction of the velocity of the water at the point (2.0 comma 4.0 ). enter an angle theta such that 0 degrees less than or equals theta less than 360 degrees . select the correct choice below and fill in any answer boxes in your choice. a. the direction is approximately nothing degrees . (round to the nearest whole number as needed.) your answer is not correct. b. the answer is undefined.
