Answer :

To calculate the force required to give an object with a mass of 125 kg an acceleration of 3 m/s², we can use Newton's Second Law of Motion. This law states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. The formula is:

[tex]\[ F = m \cdot a \][/tex]

where
[tex]\( F \)[/tex] is the force,
[tex]\( m \)[/tex] is the mass, and
[tex]\( a \)[/tex] is the acceleration.

Given:
[tex]\[ m = 125 \, \text{kg} \][/tex]
[tex]\[ a = 3 \, \text{m/s}^2 \][/tex]

We can substitute these values into the formula:

[tex]\[ F = 125 \, \text{kg} \times 3 \, \text{m/s}^2 \][/tex]

When we multiply these values together, we get:

[tex]\[ F = 375 \, \text{N} \][/tex]

Thus, the force required is 375 N.

Correct answer:
A. 375 N
