What is the mass of a crate if a force of 200 N 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 force, which is given by:

[tex]\[ F = m \times a \][/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]. Rearrange the formula to solve for [tex]\( m \)[/tex]:

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

Now, let's substitute the given values into the equation:

- Force ([tex]\( F \)[/tex]) is 200 Newtons
- Acceleration ([tex]\( a \)[/tex]) is 8 meters per second squared

Substitute these values into the rearranged formula:

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

Calculate the division:

[tex]\[ m = 25 \][/tex]

Therefore, the mass of the crate is 25 kilograms. The correct answer is 25 kg.
