F = ma,
m = F/a = 20 / 5 = 4 kg.
A force of 20 Newtons gives a brick an acceleration of 5 m/s^2. What is the mass of the brick?

To find the mass of the brick, we can apply 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 this law is:
Force = Mass x Acceleration
In this case, we know that the force is 20 Newtons and the acceleration is 5 m/s^2. Let's substitute these values into the equation:
20 N = Mass x 5 m/s^2
To solve for the mass, we need to isolate it. We can do this by rearranging the equation:
Mass = Force / Acceleration
Plugging in the given values:
Mass = 20 N / 5 m/s^2
Now, we divide 20 N by 5 m/s^2:
Mass = 4 kg
Therefore, the mass of the brick is 4 kilograms.
