Current Attempt in Progress The only force acting on a 4.6 kg body as it moves along the positive x axis has an x component Fx = -4x N, where x is in meters. The velocity of the body at x = 1.9 m is 8.9 m/s. (a) What is the velocity of the body at x = 3.3 m? (b) At what positive value of x will the body have a velocity of 4.4 m/s? (a) Number i Units (b) Number i Units
