The only force acting on a 19 kg body as it moves along the

Question

Solve the all parts of following problem:

Problem: The only force acting on a 1.9 kg body as it moves along the x axis varies as shown below. The velocity of the body at x = 0 is 4.0 m/s.

Part A: What is the kinetic energy of the body at x = 3.0 m?

J

Part B: At what value of x will the body have a kinetic energy of 8.0 J?

m

Part C: What is the maximum kinetic energy attained by the body between x = 0 and x = 5.0 m?

J

I want help to calculate the maximum kinetic energy attained by the body.
