A)more than 50 N.
B)less than 50 N.
C)50 N.

Question

To maintain a constant velocity, the applied force (in this case, the force pushing the object forward) must be equal in magnitude and opposite in direction to the force of friction. Therefore, the applied force needed to maintain a constant velocity would also be 50 N, which is the same magnitude as the force of friction acting in the opposite direction.
