Answer :
Certainly! Let's calculate the weight based on the information provided.
1. Understanding the given data:
- We know the man's mass is [tex]\( 85 \)[/tex] kg.
- The acceleration due to gravity is approximately [tex]\( 9.8 \)[/tex] m/s[tex]\(^2\)[/tex].
2. Formula to Calculate Weight:
Weight can be calculated using the formula:
[tex]\[
\text{Weight} = \text{Mass} \times \text{Acceleration due to gravity}
\][/tex]
Here, the mass is given in kilograms (kg) and the acceleration due to gravity in meters per second squared (m/s[tex]\(^2\)[/tex]).
3. Plug in the Values:
[tex]\[
\text{Weight} = 85 \, \text{kg} \times 9.8 \, \text{m/s}^2
\][/tex]
4. Perform the Multiplication:
When you multiply [tex]\( 85 \)[/tex] kg by [tex]\( 9.8 \)[/tex] m/s[tex]\(^2\)[/tex], you get:
[tex]\[
\text{Weight} = 833 \, \text{N}
\][/tex]
5. Choose the Correct Answer:
From the options provided:
- A. 145 N
- B. 833 N
- C. 85 N
- D. 725 N
The correct answer is B. 833 N.
So, the man’s weight is [tex]\( 833 \)[/tex] Newtons (N).
