A 8.2 kg object undergoes an acceleration of

2.5 m/s2.
What is the magnitude of the resultant
force acting on it?
Answer in units of N

Have you heard of the equation

F = M a?

That's the one to use.

To find the magnitude of the resultant force acting on the object, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

The formula for Newton's second law is:

Force (F) = mass (m) x acceleration (a)

Given:
Mass (m) = 8.2 kg
Acceleration (a) = 2.5 m/s^2

Substituting the given values into the formula, we get:

F = 8.2 kg x 2.5 m/s^2

Calculating the multiplication, we find:

F = 20.5 N

Hence, the magnitude of the resultant force acting on the object is 20.5 Newtons (N).
