in a plane add a 120N force at 30 degree and a -100N force at 90 degree using the parallelogram method

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

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.
