Tipler PSE5 03 58 001 (part 1 of 3) 10.0 points A particle moves in the xy plane with constant acceleration. At time zero, the particle is at x = 2 m, y = 1 . 5 m, and has velocity v o = (3 m / s) ˆ ı +(- 3 m / s) ˆ . The acceleration is given by a = (9 m / s 2 ) ˆ ı + (9 m / s 2 ) ˆ . What is the x component of velocity after 3 s? Correct answer: 30 m / s. 002 (part 2 of 3) 10.0 points What is the y component of velocity after 3 s? Correct answer: 24 m / s. 003 (part 3 of 3) 10.0 points What is the magnitude of the displacement from the origin ( x = 0 m, y = 0 m) after 3 s? Correct answer: 61 . 1658 m.
