Head-on Inelastic Collision Final Velocity Calculator

Head-on Inelastic Collision Final Velocity Calculator

Calculate the final velocity after a head-on inelastic collision using:
\[ v_{f} = \frac{m_1v_1 + m_2v_2}{m_1+m_2} \]

* Enter masses in kilograms (kg) and velocities in meters per second (m/s). Use sign conventions to indicate direction.

Step 1: Enter Parameters

Example: 2 kg

Example: 4 m/s (positive for one direction)

Example: 3 kg

Example: -2 m/s (negative indicates opposite direction to \( v_1 \))

Formula: \( v_{f} = \frac{m_1v_1 + m_2v_2}{m_1+m_2} \)


Practical Example:
For \( m_1 = 2\,\text{kg} \), \( v_1 = 4\,\text{m/s} \), \( m_2 = 3\,\text{kg} \), and \( v_2 = -2\,\text{m/s} \):
\[ v_{f} = \frac{2\times4 + 3\times(-2)}{2+3} = \frac{8-6}{5} = \frac{2}{5} = 0.4\, \text{m/s}. \]
