An object ends up at a final
position of x = -55.25 meters after
a displacement of -189.34 meters.
what was its initial position?
(unit = m)

Write the correct abbreviation for each metric unit

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.

What are two different ways you could find the value of a? explain these methods.
