A 10 g block slides with a velocity of 20 cm/s on a smooth level surface and makes a collision with a 30 g block moving in the opposite direction with a velocity of 10 cm/s. If the collision is perfectly elastic, what is the velocity of the 30 g block after the collision?
- A. 15 cm/s
- B. 10 cm/s
- C. 25 cm/s
- D. 5 cm/s
The velocity of the 30 g block after the collision is 5 cm/s.
