A young boy playing sipa in a local barangay kocks a small steel washer (used as the sipa ball) weighing 0.5kg with a force of 150 N. What is the force the the steel washer exerts on the body foot? What happens to the steel washer after the force is applied

In this scenario, the boy applies a force of 150 N to the steel washer when kicking it. According to **Newton's Third Law of Motion**, every action has an equal and opposite reaction. This means that the force the steel washer exerts on the boy's foot is also **150 N** but in the opposite direction. This law ensures that forces come in pairs—action and reaction—acting on two different objects.

### What happens to the steel washer after the force is applied?

Once the boy applies a force to the washer, the washer accelerates. According to **Newton's Second Law of Motion**, the acceleration (\(a\)) of the washer can be calculated by the equation:

\[
F = ma
\]

Where:
- \(F\) is the force applied (150 N),
- \(m\) is the mass of the washer (0.5 kg),
- \(a\) is the acceleration.

We can rearrange this equation to solve for \(a\):

\[
a = \frac{F}{m} = \frac{150 \, \text{N}}{0.5 \, \text{kg}} = 300 \, \text{m/s}^2
\]

So, the steel washer accelerates at **300 m/s²** in the direction of the applied force. After the force is applied, the washer moves upward into the air at an initial acceleration of 300 m/s², assuming air resistance is negligible.
