Multiple-choice questions may continue on the next column or page find all choices before answering. 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 = 5 . 5 m, y = 8 . 5 m, and has velocity vectorv o = (1 . 5 m / s) + (- 9 m / s) . The acceleration is given by vectora = (7 m / s 2 ) + (4 . 5 m / s 2 ) . What is the x component of velocity after 5 s? Answer in units of m / s. 002 (part 2 of 3) 10.0 points What is the y component of velocity after 5 s? Answer in units of 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 5 s? Answer in units of m. 004 10.0 points A plane drops a hamper of medical supplies from a height of 3850 m during a practice run over the ocean. The planes horizontal veloc- ity was 133 m / s at the instant the hamper...
