10. The tolerance is -+1 in the 2nd significant digit.

A 2.4 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) = (6.2 - x2 )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 = 2.6 m? (b) What is the maximum kinetic energy of the block between x = 0 and x = 2.6 m? (a) Number i Units (b) Number i Units
