Answer:
The final velocity of apple and arrow after the collision is 2 m/s.
Explanation:
Given that,
Mass of an arrow, m = 0.5 kg
Initial velocity of the arrow, v = 10 m/s
Mass of an apple, m' = 2 kg
Initial velocity of the arrow, v' = 0 (at rest)
We need to find the final velocity of apple and arrow after the collision. After the collision, the arrow and the apple are stuck together. It is a case of inelastic collision. Let V is the final velocity of apple and arrow after the collision. Using the conservation of linear momentum as :
So, the final velocity of apple and arrow after the collision is 2 m/s.
