Answer in units of N

34

To find the net force on the block with a mass of 4.7 kg, we need to calculate the sum of all forces acting on the block.

The only force acting on the block is the horizontal force of 696 N applied to it. Therefore, the net force on the block with a mass of 4.7 kg is equal to the applied force of 696 N.

So, the net force on the block with mass 4.7 kg is 696 N.
