Problem 8.8: An explosive collision
Please wait for the animation to completely load.
A spring that is attached to the end of a cart is compressed, and the cart is placed next to another cart on a low-friction track. The spring is released such that the two carts are "pushed" apart as shown in the animation (position is given in meters and time is given in seconds). The mass of the green cart is 1.35 kg, and the mass of the orange cart is 0.9 kg. Restart.
- What is the magnitude of the momentum of the green cart after the collision?
- What is the magnitude of the momentum of the orange cart after the collision?
- What is the change in momentum of the system due to the release of the spring?
- What is the change in kinetic energy of the system due to the release of the spring?
