Question

A toy helicopter flies forward with a force of 15 N into an oncoming wind of 10 N. The force ofgravity pulls the helicopter down with a force of 5 N, but the propeller is providing an upwardforce of 10 N.
Which of the following accurately describes the helicopter’s force?
(1 point)
The toy helicopter is flying forward with a force of 5 N and upward with a force of 5 N.
The toy helicopter is flying forward with a force of 10 N and upward with a force of 5 N.
The toy helicopter is flying forward with a force of 15 N and upward with a force of 10 N.
The toy helicopter is flying forward with a force of 15 N.

Answer 1

To determine the net forces acting on the toy helicopter, we need to consider both the forward forces and the vertical forces.

1. **Forward Forces:**
- The helicopter has a forward thrust of 15 N.
- There is an opposing wind force of 10 N.

Therefore, the net forward force is:
\[
\text{Net Forward Force} = \text{Thrust} - \text{Wind} = 15 \, \text{N} - 10 \, \text{N} = 5 \, \text{N}
\]

2. **Vertical Forces:**
- The propeller provides an upward force of 10 N.
- Gravity pulls the helicopter down with a force of 5 N.

Therefore, the net upward force is:
\[
\text{Net Upward Force} = \text{Upward Force} - \text{Gravity} = 10 \, \text{N} - 5 \, \text{N} = 5 \, \text{N}
\]

Putting this information together:
- The toy helicopter is flying forward with a net force of **5 N**.
- The toy helicopter is flying upward with a net force of **5 N**.

So, the correct answer is:
**The toy helicopter is flying forward with a force of 5 N and upward with a force of 5 N.**
