A horizontal net force is exerted on a 2.0kg object at rest. The object starts at x=0m and travels 6.0m along a horizontal frictionless surface. The net force F as a function of the object's position x s shown below. Net horizontal force (N) vs. horizontal position (m) graph. Y-intercept is zero and it has a slope of 5 m/s. What is the velocity of the object? Round answer to 2 significant digits.
