A 0.75 kg toy car moving with a speed of 3 m/s to the right collides with a 0.25 kg toy car moving with a speed of 3 m/s to the left. The two collide and the 0.25 kg toy car ends with a speed of 5 m/s to the right. What is the final speed of the 0.75 kg car? Is this collision elastic? Explain.

Did you know that in a collision between two objects, the Law of Conservation of Momentum states that the total momentum before the collision is equal to the total momentum after the collision? In the given scenario, the 0.75 kg toy car initially has a momentum of (0.75 kg) x (3 m/s) = 2.25 kg·m/s to the right, while the 0.25 kg toy car has a momentum of (0.25 kg) x (-3 m/s) = -0.75 kg·m/s to the left. After the collision, the 0.25 kg toy car has a momentum of (0.25 kg) x (5 m/s) = 1.25 kg·m/s to the right. To find the final speed of the 0.75 kg car, we use the principle of conservation of momentum: (0.75 kg) x v = 2.25 kg·m/s - 1.25 kg·m/s. Solving for v, we get v = (2.25 kg·m/s - 1.25 kg·m/s) / 0.75 kg = 1 m/s to the right. Therefore, the final speed of the 0.75 kg car is 1 m/s to the right. The collision is not elastic because there is a loss of kinetic energy in the collision.
