What is the force required to move a load 50kg through a distance of 1000cm in 5 seconds

Based on the 2nd law of motion, the force is a product of the mass and acceleration. We are already given with the mass and the acceleration is calculated by the following equation,
                            d = Vot + 0.5at²
where d is distance (equal to 1 m), Vo is the initial velocity (equal to 0), a is acceleration, and t is time. 

Substituting the known values,
                            1 m = 0 + 0.5(a)(5 s)²
The value of a is equal to 0.08 m/s².

Now, calculating for force,
                             F = m x a 
                              F = (50 kg)(0.08 m/s²)
                               F = 0.32 N

Thus, the force needed to move the load is 0.32N.
