1575 N

Explanation:

Step 1:

Let us consider that 350 J of energy is spent by that person to push a couch to 4.5 m from its initial position.

Let F be the force required and E be the energy spent and D be the distance traveled by the couch from its initial state.

In Physics, Work done = Force / Displaced distance

Step 2:

Let the work done be 350 J and Distance be 4.5 m

Then Force exerted = $350*4.5 = 1575 N$
