Question: A 3.00-kg object has a velocity (6.00i 2.00j) m/s. (a) What is its kinetic energy at this time? (b) Find the total work done on

A 3.00-kg object has a velocity (6.00i ─ 2.00j) m/s.
(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.)
