Force equals mass*acceleration
F = ma
Given m = 54.87 kg, a = 9.8 m/s^2
F = (54.87)(9.8)
F = 537.726
F = 538 N
A force of al least 538 Newtons is required to move the object.
I believe that the answer to this would be option C. Since sandstones are not commonly seen among river beds, the condition that would make us easier to understand as to what happened to this is how fast the river was flowing. Due to the pressure of the river, this brought other sediments with it most especially sandstones.
