Kindly check ATTACHED PICTURE for complete solution.
Answer:
The correct answer is option a.
Explanation:
Conservation of momentum :
Where :
= masses of object collided
= initial velocity before collision
= final velocity after collision
We have :
Two equal-mass carts roll towards each other.
Initial velocity of
Initial velocity of (opposite direction)
Final velocity of (same direction )
Final velocity of (same direction)
v = 0.5 m/s
rg135
The speed of the carts after their collision is 0.5 m/s.
