The x - and y -components of an acceleration vector are 3.0 m/s 2 and 4.0 m/s 2 , respectively. (a) The magnitude of the acceleration vector is (1) less than 3.0 m/s 2 , (2) between 3.0 m/s 2 and 4.0 m/s 2 , (3) between 4.0 m/s 2 and 7.0 m/s 2 , (4) equal to 7.0 m/s 2. (b) What are the magnitude and direction of the acceleration vector
