Final answer:
The net force in this scenario is 862 Newtons.
Step-by-step explanation:
The net force in this scenario can be calculated by subtracting the force of friction from the applied force. In this case, the applied force is 1156 Newtons and the force of friction is 294 Newtons. Therefore, the net force is 1156 N - 294 N = 862 Newtons. So, the correct answer is (a) 862 Newtons.
