The only force acting on a 2.7 kg body as it moves along the positive x axis has an x component Fx = - 6x N, where x is in meters. The velocity of the body at x = 3.0 m is 8.0 m/s. What is the velocity at x = 4? I found it to be 0.22m/s but my friends swear up and down it's not. Could I get a second opinion on this answer? My work is something like this: F = -6x a = -6/2.7 * x v = -3/2.7 * x^2 +c v(3) = 8 8 = -3/2.7 * 3^2 + c c = 18 v(4) = -3/2.7 * 4^2 + 18 v(4) = 0.222 Corrections please? Thanks in advance.
