A 3 kg crate with initial velocity velocity of 13 m/s (to the right horizontal) from point A to point D ( end of last frictional surface) over three different frictional surfaces, each surface is 1 m long With the first surface having a coefficient of kinetic friction between the floor and the crate is Uk= 0.1, the second is Uk= 0.2, and the last is Uk= 0.1. What is the speed at point D? Using the principle of work and energy.
