A cart of mass 4 kg is on frictionless surface and compressed against an ideal spring with spring constant 192 N/m for a distance of 1.04 m. After it is released, it hits a second cart of mass 8 kg and bounces back while the second car continues traveling onto a ramp where it reaches a height of h₂ = 0.67 m. Find the velocity of the second cart in m/s immediately AFTER being hit by the first cart. Use g = 9.8 m/s² and retain your answer to two decimal places.

Question
**Problem Description:**

A cart of mass 4 kg is on a frictionless surface and compressed against an ideal spring with a spring constant of 192 N/m for a distance of 1.04 m. After it is released, it hits a second cart of mass 8 kg and bounces back while the second cart continues traveling onto a ramp where it reaches a height of \( h_2 = 0.67 \, \text{m} \). Find the velocity of the second cart in m/s immediately AFTER being hit by the first cart. Use \( g = 9.8 \, \text{m/s}^2 \) and retain your answer to two decimal places.

**Diagrams Explanation:**

The first diagram shows a cart (\( m_1 \)) of mass 4 kg compressed against a spring with spring constant \( k = 192 \, \text{N/m} \). The spring is on a horizontal frictionless surface. 

The second diagram shows the same cart (\( m_1 \)) traveling towards a second cart (\( m_2 \)) of mass 8 kg on the horizontal surface after being released from the spring. The second cart (\( m_2 \)) then moves up a ramp, reaching a height (\( h_2 \)) of 0.67 m. 

The task is to calculate the velocity of the second cart (\( m_2 \)) immediately after being hit by \( m_1 \).
