8. [1pt] * * * Hint: When finding the area under the F(x) graph, the sign of the work will depend on whether F(x) is positive or negative. A body of mass 9.57 kg and velocity 7.59 m/s moves in the positive x direction on a horizontal frictionless surface. At x = 0, it comes under the influence of a force acting along the same axis. The force varies with position as shown. How much work is done by the force as the block moves from the origin to 8 m? 10 + 5 Force (N) -5 2 3 6 7 Position (m) Answer: Submit All Answers 9. [1pt] * ww Hint: This is very easy if you have found the correct answer to the previous question. What is the kinetic energy of the body at x = 8 m? Answer: Submit All Answers
