What is the mass of a crate if a force of 200 N causes it to accelerate at 8 m/s²? (Use the 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 Newton's second law of motion. The formula for this is:

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

Where:
- [tex]\( F \)[/tex] is the force applied to the object (in Newtons, N).
- [tex]\( m \)[/tex] is the mass of the object (in kilograms, kg).
- [tex]\( a \)[/tex] is the acceleration of the object (in meters per second squared, m/s²).

We are given:
- A force ([tex]\( F \)[/tex]) of 200 N.
- An acceleration ([tex]\( a \)[/tex]) of 8 m/s².

We need to find the mass ([tex]\( m \)[/tex]) of the crate.

Rearrange the formula to solve for mass ([tex]\( m \)[/tex]):

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

Now substitute the given values into the formula:

[tex]\[ m = \frac{200\, \text{N}}{8\, \text{m/s²}} \][/tex]

Calculate:

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

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

The mass of the crate is 25 kg.
