Tension force refers to an object being pulled tight from both ends. Think about pulling a rope or string. This type of force is only exerted if the string is taut. Grasp the two ends of the string, and pull them so the string is taut. How does this force, the tension force, differ from elastic force?

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.
