Physics The force shown in the figure acts on a 0.44 kg object that moved along the x axis. Assume the force is a constant 0.70 N (to the right) frok x = 0m to x = 3.0 m. Then assuke the force will decrease linearly from 0.70 N at x = 3.0 m to 0 N at x = 7.0 m Part A) suppose the object moved from xi = 1.0 m with an initial speed vi = 4.5 m/s to xf = 4m. what is the final speed of the object at 4.0 m? Part B) Suppose the object moves from xi = 2.7m with an initial speed of vi = 2.5 m/s to xf = 0.79 m. What is the final speed of the object at x = 0.79m? Force (N ) 0 60 -+ s cash E Z
