Answer:
The given data presents an exciting physics experiment where two carts collide on a frictionless track and stick together. Let's delve into the dynamics of momentum and kinetic energy to understand the outcomes of the collision.
Total Momentum Calculation:
Before the collision, Cart 1 with a mass of 625 g and a speed of 2.9 m/s has a momentum. Cart 2, with a mass of 210 g and a speed of -3.6 m/s (opposite direction), also possesses momentum. By adding these individual momenta, we find the total momentum of the system before collision.
