Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

An object has a velocity (3.5 m/s)i + (-4.76 m/s)j + (4.68 m/s)k. In a time of 3.21 s its velocity becomes (-3.79 m/s)i + (0.00 m/s)j + (4.68 m/s)k.

If the mass of the object is 6.4 kg, what is the magnitude of the net force on the object, in N, during the 3.21 s? Assume the acceleration is constant.
