A 3.00-kg object has a velocity (6.00i 2.00j) m/s. (a) What is its kinetic energy at this
Question:
(a) What is its kinetic energy at this time?
(b) Find the total work done on the object if its velocity changes to (8.00i + 4.00j) m/s. (Note: From the definition of the dot product, v2 = v ∙ v.)

I have worked with very different types of students, from little kids to bussines men and women. I have thaught at universities, schools, but mostly in private sessions for specialized purpuses. Sometimes I tutored kids that needed help with their classes at school, some others were high school or college students that needed to prepare for an exam to study abroud. Currently I'm teaching bussiness English for people in bussiness positions that want to improve their skills, and preparing and ex-student to pass a standarized test to study in the UK.
