A box of mass 2.4 kg is sliding along the horizontal floor, with an initial velocity of 3.4 i m/s. There is a pushing force P = 16.8 i N pushing it, and a kinetic friction force Fk = -8.0 i N opposing motion. +y +X P- m FK Draw a free body diagram of the forces acting on the box. Calculate the net work done on the box, assuming it moves 2.3 metres. Use this to calculate the final speed of the box. Enter this result in the answer box, in m/s to 2 significant figures.
