The next two questions refer to the following situation: Two masses travel at the same speed, and they collide at the origin. After the collision, the two masses are stuck together. The mass, M₁, of the object traveling in the positive x-direction is 1 kg. After the collision the combined masses travel at 30° with respect to the x-axis, as shown. 2. The kinetic energy after the collision is + 0=30° Equal to the kinetic energy before the collision. OSmaller than the kinetic energy before the collision. Larger than the kinetic energy before the collision.
