Three blocks are in contact with each other

on a frictionless horizontal surface. A 417 N
horizontal force is applied to the block with
mass of 3.7 kg as shown in the figure below.
The acceleration of gravity is 9.8 m/s^2.
(the picture looks like this)

*----->[3.7 kg][5.1 kg][7 kg]
What is the net force on the block with
mass 3.7 kg?
Answer in units of N

To find the net force on the block with a mass of 3.7 kg, we need to consider the forces acting on it.

In this scenario, the only force acting on the block is the applied horizontal force of 417 N (as shown by the arrow on the left side of the figure). Since there is no friction mentioned, we can assume that there is no other force opposing the applied force.

Therefore, the net force on the block with a mass of 3.7 kg is simply the applied force of 417 N.

So, the net force on the block with a mass of 3.7 kg is 417 N.
