A 0.20 kg object moves along a striaght line. The net force acting on the object varies with the object's displacement. The object starts from rest at displacement X = 0 and time t = 0 and is displaced a distance of 20 m. Determine each of the following. A. The acceleration of the particle when its displacement x is 6 m B. The time taken for the object to be displaced the first 12 m C. The amount of work done by the net force in displacing the object the first 12 m D. The speed of the object at displacement X = 12 m E. The final speed of the object at displacement X = 20 m F. The change in the moentum of the object as it is displaced from x = 12 m to x = 10 m these equations are the ones I THINK are with the problem VF = Vo + at Vf2 = vo2 + 2ad (Final Velocity squared = Initial Velocity squared + 2 x acceleration x distance) D = Vot + 1/2 at2 ( Initial Velocity x Time + 1/2 x acceleration x time squared) Im not really sure where to start with this as I have not really been explained very well what displacement and net force is. Any help is appreciated.
