Seed Dropped by a Bird#

A bird gliding at a constant 5 \(m/s\) drops an apple seed from its beak.

Part 1#

Assuming air resistance is negligible and that the bird maintains its velocity, when the seed hits the ground the bird is:

Answer Section#

  • directly overhead.

  • well in front of the seed.

  • well behind the seed.

Part 2#

Is the final speed of the seed bigger or smaller than the bird’s speed just before the seed hits the ground? Explain your answer.

Answer Section#

  • The final speed of the seed is bigger than the bird’s speed because despite having the same horizontal velocity component as that of the bird, it also has a large vertical component.

  • The final speed of the seed is smaller than the bird’s speed because the bird is no longer pulling it.

  • The final speed of the seed is the same as the bird’s speed.

  • The final speed of the seed is smaller than the bird’s speed because the bird maintains its horizontal speed.
