Answer:
34 m/s2 at 34.1º north of east
Explanation:
A particle has an initial velocity of 4.8 m/s toward the south and a final velocity of 7.1 m/s toward the east. The particle was subject to a constant acceleration for 0.25 s. The magnitude and the direction of the acceleration must have been 34 m/s2 at 34.1º north of east
