Work/energy problem with friction (video) | Khan Academy
Since friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s.

Introduction to work and energy (video) | Khan Academy
The actual formula for work is. W = F · s, i.e. Work is the scalar product of the vectors Force and displacement, not necessarily distance. Scalar product is so called because it returns a scalar, which in this case is Work. (It is also called "dot product" because of the "·" symbol between the vectors in the formula.)
Dynamics Problem Solving Video Exam and Tutorial
This video shows 50 original and carefully designed problems in high quality MP4 video format, which can provide about 2½ hours of problem solving practice. After each exercise is presented to the students as a multiple choice question, the video needs to be paused for about two minutes, to give time to the students to solve the problem on their own.
