Force F=64Newtons.
Explanation:
This case is taken as Motion of block on a rough fixed horizontal surface.
In this case, if the block slides or moves with an acceleration under the influence of an external force 'F', the acceleration of the block is
Now substituting the values we get
F = (5)(12) + 4
