    Smooth surface is the same as "friction is neglected." We can use Force = mass * acceleration of F = m*a = 4*15 = 60N.

    This is very simple because the force F acts directly on the block in the direction of motion. There is no angle to consider. Hope this helps. Please award Best Answer to the best answer.

    F = m*a = 4*15 = 60 N , since F // to the ground
