What force is required to keep a 245kg wood pallet moving at a constant speed across a concrete floor

The required force is

(245 kg) x (9.8 m/s²) x (coefficient of kinetic friction between the pallet and the concrete floor.

Force = 2401 μ  Newtons

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

the bal will not change its velocity.
