Three toy boats with the same mass were in a lake. Two boats were moving and one was stopped. Each boat got bumped by another boat, but not in the same direction. All the boats changed speed as a result of being bumped. Use the information in the diagram to answer.
Which toy boat(s) experienced the strongest force when it was bumped? How do you know?
a The blue toy boat experienced the strongest force because it takes a stronger force to slow something down than it takes to speed something up.
b The gray toy boat experienced the strongest force because it had the fastest ending speed.
c The orange and gray toy boats experienced the strongest forces because they both gained the same force as they sped up. The blue boat lost force, so it slowed down.
d All three toy boats experienced the same strength force because they changed speed by the same amount.
