Answer:

F = 0

Explanation:

Newton's Second Law tells us, that the sum of the forces acting on the body is equal to mass by acceleration. If a body moves at constant speed, it is because there is no external force that tends to increase or decrease speed.

That is, when there is constant velocity, acceleration is equal to zero.

F = m*a

where:

m = mass [kg]

a = acceleration [m/s^2]

Now if v = constant, a = 0

F = m * a = m *0 = F = 0
