3. A jogger runs 300 m due west and then turns and runs 500 m due south. a) What is the total distance that she ran? 800 b) What is her total displacement? c) If it takes her 135 s to complete the route, calculate her speed and velocity.

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.
