A 4.7 kg block is initially at rest on a horizontal frictionless

A 4.7 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) = (8.8 - x)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 = 4.4 m? (b) What is the maximum kinetic energy of the block between x=0 and x 4.4 m? (a) Number i Units (b) Number i Units
