To analyze the forces acting on the helicopter, let's break down the forces involved:
-
Forward forces:
- Toy helicopter's forward thrust: 15 N
- Oncoming wind resistance (force opposing the thrust): 10 N
The net forward force can be calculated as: \[ \text{Net forward force} = 15 , \text{N} - 10 , \text{N} = 5 , \text{N} \]
-
Vertical forces:
- Upward force from the propeller: 10 N
- Downward force due to gravity: 5 N
The net upward force can be calculated as: \[ \text{Net upward force} = 10 , \text{N} - 5 , \text{N} = 5 , \text{N} \]
Based on this analysis:
- The helicopter is flying forward with a net force of 5 N.
- The helicopter is also moving upward with a net force of 5 N.
Thus, the option that accurately describes the helicopter's force is:
The toy helicopter is flying forward with a force of 5 N and upward with a force of 5 N.
