Question

What is the gravitational force of a tree branch falling out of a tree that has a mass of 129 kg?

A) 1,260 N
B) 1,270 N
C) 1,310 N
D) 1,250 N

Answer 1

The gravitational force of a tree branch with a mass of 129 kg is calculated using the formula F = m × g. The force comes out to 1264.2 N, and the closest answer to this is 1,270 N (Option B).

Step-by-step explanation:

The question is asking to calculate the gravitational force of a tree branch with a given mass as it falls out of a tree. To find the gravitational force (often called weight), we can use the formula:

F = m × g

Where:

• F is the force in newtons (N)
• m is the mass of the object in kilograms (kg)
• g is the acceleration due to gravity (9.8 m/s² on Earth)

Plugging in the mass of the tree branch (129 kg) we get:

F = 129 kg × 9.8 m/s²
= 1264.2 N

Therefore, the closest answer to our calculation is:

Option B) 1,270 N
