Question

The drawing shows a hot air balloon. The mass of the balloon is 3000kg. 34000N

What is the weight? What is the resultant force on the balloon?

Answer 1

Weight =29400N

Resultant force = 4600N upwards

Step-by-step explanation:

The weight of an object is calculated using the formula:

`W = mg`

where W = weight (N), m = mass (kg) and g = gravitational field strength (N/kg).

Since the hot air balloon has a mass of 3000kg and the field strength of the Earth is 9.8N/kg, the weight of the balloon is:

`3000kg* 9.8N/kg = 29400N`

The second part of your question asks about the resultant force of the hot-air balloon. This can be calculated by subtracting the smaller magnitude of force from the larger magnitude. This means the resultant force is:

`34000N-29400N = 4600N`

Therefore, the hot-air balloon has a resultant force of 4600N upwards.

Hope this helps!!!
