Answer:
Net force is always m•a. In this case, the velocity is constant so the acceleration is zero and the net force is zero. Constant velocity motion can always be associated with a zero net force.

Given - Mass and constant velocity
Find - Force
Solution - Force is calculated by finding the product of mass and acceleration. Acceleration is the rate of change of velocity.
As per the question, the velocity is constant. Hence, acceleration will be zero. Further, as per the given formula, force will also be zero.
So, amount of force required is 0 (zero).
