# Question: Two blobs of space debris collide in a perfectly elastic, one-dimensional collision. If the red blob has a mass of 6.41 kg and is initially traveling at 16.6 m/s, and the green blob, with a mass of 8.38 kg, is initially at rest, what are their speeds immediately after the collision? -Free Course Hero Question Answer.

Question Description: Two blobs of space debris collide in a perfectly elastic, one-dimensional collision. If the red blob has a mass of 6.41 kg and is initially traveling at 16.6 m/s, and the green blob, with a mass of 8.38 kg, is initially at rest, what are their speeds immediately after the collision?

Speed of green blob after collision = 14.389 m/s

Speed of red blob after collision = – 2.21 m/s

Minus sign for opposite direction to initial motion of blob

**Course Hero** **Answer & Explanation**:

Speed of green blob after collision = 14.389 m/s

Speed of red blob after collision = – 2.21 m/s

Minus sign for opposite direction to initial motion of blob
