Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.

Question

A mass \( m_A = 2 \, \text{kg} \) slides down a slippery ramp, reaching a speed \( v = 10 \, \text{m/s} \) at the bottom. After reaching the level ground, \( m_A \) collides with mass \( m_B = 3 \, \text{kg} \) at the bottom, sticking together in a perfectly inelastic collision.

a.) What was the height of the ramp, assuming that \( m_A \) started from rest?

b.) How fast were the combined masses \( m_A \) and \( m_B \) moving after sticking together?

c.) The combined mass runs into a spring, which brings it to a stop after being compressed 7 cm. What is the spring constant \( k \)?
