To determine the final speed of two 4-kilogram masses after an elastic collision, we need to know the initial speeds of both masses before the collision. An elastic collision conserves both momentum and kinetic energy.
However, without additional information about the initial velocities of the two masses, we can't calculate their final speeds.
If you provide the initial velocities, we can use the following principles:
1. **Conservation of Momentum:**
\[
m_1 u_1 + m_2 u_2 = m_1 v_1 + m_2 v_2
\]
where \( m_1 \) and \( m_2 \) are the masses, \( u_1 \) and \( u_2 \) are the initial velocities, and \( v_1 \) and \( v_2 \) are the final velocities.
2. **Conservation of Kinetic Energy:**
\[
\frac{1}{2} m_1 u_1^2 + \frac{1}{2} m_2 u_2^2 = \frac{1}{2} m_1 v_1^2 + \frac{1}{2} m_2 v_2^2
\]
If you can provide the initial speeds or directions, I can help calculate the final speeds after the collision.
