Answer

Brief Explanations:

  1. For the bird - When the wind direction changes from North to Northeast, a change in the bird's motion situation occurs. According to Newton's first law, a change in motion requires a force. So, a force is exerted on the bird.
  2. For Jim's bike - When Jim puts on the brakes, the bike slows down. A change in velocity (deceleration) means a force (friction force from the brakes) is exerted on the bike.

Answer:

For the bird: a. Yes For the bike: a. Yes
