What is the mass of a crate if a force of [tex]$200 \, \text{N}$[/tex] causes it to accelerate at [tex]$8 \, \text{m/s}^2$[/tex]? (Formula: [tex]$F = ma$[/tex])

A. 25 kg
B. 192 kg
C. 208 kg
D. 16 kg

Answer :

To find the mass of the crate, we can use the formula for Newton's second law of motion:

[tex]\[ F = ma \][/tex]

where:
- [tex]\( F \)[/tex] is the force applied (in Newtons),
- [tex]\( m \)[/tex] is the mass of the object (in kilograms),
- [tex]\( a \)[/tex] is the acceleration of the object (in meters per second squared).

In the problem, we have:
- A force [tex]\( F \)[/tex] of 200 Newtons,
- An acceleration [tex]\( a \)[/tex] of 8 meters per second squared.

We need to solve for the mass [tex]\( m \)[/tex]. We can rearrange the formula to solve for mass:

[tex]\[ m = \frac{F}{a} \][/tex]

Substitute the given values into the equation:

[tex]\[ m = \frac{200 \, \text{N}}{8 \, \text{m/s}^2} \][/tex]

Calculate the mass:

[tex]\[ m = 25 \, \text{kg} \][/tex]

Therefore, the mass of the crate is 25 kg.
