A1.1 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 with arrow(x) = (2.4 − x2)i hat 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 and x = 2.0 m?
