------------------------------------------------ What is the mass of a crate if a force of 200 N causes it to accelerate at [tex]$8 \, m/s^2$[/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 when a force of 200 N causes it to accelerate at [tex]\(8 \, \text{m/s}^2\)[/tex], we can use the formula:

[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 (in meters per second squared).

We need to solve for the mass [tex]\( m \)[/tex]. Rearranging the formula gives us:

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

Now, let's plug in the known values:

- [tex]\( F = 200 \, \text{N} \)[/tex] (the force applied),
- [tex]\( a = 8 \, \text{m/s}^2 \)[/tex] (the acceleration).

Substituting these into the formula:

[tex]\[ m = \frac{200}{8} \][/tex]

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

Therefore, the mass of the crate is [tex]\( 25 \, \text{kg} \)[/tex].
