The only force acting on a $2.0\mathrm{kg}$ 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 $F_5=4.0\mathrm{N}$. The velocity of the body at $x=0$ is $7.0\mathrm{m}/\mathrm{s}$. (a) What is the kineticenergy of the body at $x=3.0\mathrm{m}$ ? (b) At what value of $x$ will the body have a kineticenergy of $24.5\mathrm{J}$ ? (c) What is the maximum kineticenergy of the body between $x=0$ and $x=5.0$ $\mathrm{m}$ ?
