A 2.7 kg block is initially at rest on a horizontal frictionless surface when a horizontal force in the positive direction of an x axis is applied to the block. The force is given by F→(x)=(8.6-x2)î⁢N, where x is in meters and the initial position of the block is x = 0. (a) What is the kinetic energy of the block as it passes through x = 3.9 m? (b) What is the maximum kinetic energy of the block between x = 0 and x = 3.9 m?
