A 3.3 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) = (7.4-x²) 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 3.8 m? (b) What is the maximum kinetic energy of the block between x=0 and x-3.8 m? (a) Number (b) Number Units Units
