Suppose you push a box, which is then slowed to rest by friction. Given displacement = 2m, time = 2.29s, and mass of box = 300 g, find Work done by friction to stop the box and initial kinetic energy

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.
