Question

Four forces act on a hot-air balloon, shown from the side in the figure below. Find the magnitude and direction of the resultant force on the balloon if F1 = 5050 N, F2 = 1450 N, F3 = 950 N, and F4 = 4050 N. how many degress clockwise of f2

Answer 1

The magnitude of the resultant force on the balloon is 1118 N.

From the given information, we know that four forces act on a hot-air balloon, and we need to find the magnitude and direction of the resultant force on the balloon. The magnitudes of the four forces are given as F1 = 5050 N, F2 = 1450 N, F3 = 950 N, and F4 = 4050 N. However, the direction of each force is not given, so we cannot determine the direction of the resultant force.

To find the magnitude of the resultant force, we can use the Pythagorean theorem to add the vector components of the four forces. The vector components of each force can be found by resolving them into horizontal and vertical components. Assuming that F1 and F4 act vertically and F2 and F3 act horizontally, we can write:

Fx = F2 - F3

Fy = F1 - F4

where Fx and Fy are the horizontal and vertical components of the resultant force, respectively.

Substituting the given values, we get:

Fx = 1450 N - 950 N = 500 N

Fy = 5050 N - 4050 N = 1000 N

Using the Pythagorean theorem, we can find the magnitude of the resultant force:

`|F| = sqrt(Fx^2 + Fy^2)\\= sqrt((500 N)^2 + (1000 N)^2)\\= 1118 N`

Therefore, the magnitude of the resultant force on the balloon is 1118 N.
