A 1.5 kg block is initially at rest on a horizontal frictionless surface when a horizontal force along the x-axis is applied to the block. The force is given by F(x)=(2.5−x 2) i^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 = 2.0 m? (b) What is the maximum kinetic energy of the block between x = 0 to x = 2.0 m?
