Two low-friction physics demo carts collide on a horizontaltrack. The first cart, with a mass of 0.154 kg , is moving to theright with a speed of 0.810 m/s . The second cart, with a mass of0.299 kg , is moving to the left with a speed of 2.21 m/s . Thecarts collide in an elastic collision, such that the total kineticenergy after the collsion is equal to the total kinetic energybefore the collision.
1. What is the final speed of the 0.154 kg cart?
2. What is the direction of the final velocity of the 0.154 kgcart?
3. What is the final speed of the 0.299 kg cart?
4. What is the direction of the final velocity of the 0.299 kgcart?
