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 :

Sure! Let's solve this step-by-step:

1. Identify the given values:
- Force (F) = 200 Newtons (N)
- Acceleration (a) = 8 meters per second squared (m/s²)

2. Identify the formula needed:
- We will use the formula [tex]\( F = ma \)[/tex], where:
- [tex]\( F \)[/tex] is the force,
- [tex]\( m \)[/tex] is the mass,
- [tex]\( a \)[/tex] is the acceleration.

3. Rearrange the formula to solve for mass (m):
- [tex]\( m = \frac{F}{a} \)[/tex]

4. Substitute the given values into the formula:
- [tex]\( m = \frac{200 \, \text{N}}{8 \, \text{m/s}^2} \)[/tex]

5. Perform the division:
- [tex]\( m = 25 \, \text{kg} \)[/tex]

So, the mass of the crate is 25 kg.

This means that a force of 200 N causes a crate with a mass of 25 kg to accelerate at [tex]\( 8 \, \text{m/s}^2 \)[/tex].
