The only force acting on a 2.0 kg body as the body moves along an x axis varies as shown in the figure. The scale of the figure's vertical axis is set by F, - 4.0 N. The velocity of the body at x = 0 is 6.0 m/s. (a) What is the kinetic energy of the body at x - 5.0 m? (b) At what value of x will the body have a kinetic energy of 19.0 J? (c) What is the maximum kinetic energy of the body between x = 0 and x = 5.0 m? F. (N) 2 0 x (m)
