The only force acting on a `2.0-kg` body as it moves along the x-axis varies as shown in figure. The velocity of the body at `x=0` is `4.0ms^-1`.

a. What is the kinetic energy of the body at `x=3.0m`?
b. At what value of x will the body have a kinetic energy of `8.0J`?
c. What is the maximum kinetic energy attained by the body between `x=0` and `x=5.0m`?
