How do you find the total position, and total acceleration from a velocity-time graph?

Distinguish between a transverse wave and a longitudinal wave.

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.

Explain what it means to view something from a frame of reference. provide an example that illustrates your explanation. (4 points)
