Question 2 • Physics

Alyssa is carrying a water balloon while running down a field at a speed of 14 meters per second She tosses the water balloon forward toward a bucket with a speed of 23 meters per second Alyssa’s friend Naya is standing still next to the field. Which statement is supported by this scenario?

Answer
A
The speed of the balloon is 23 meters per second for Alyssa and 37 meters per second for Naya.
B
The speed of the balloon is 23 meters per second for Alyssa and 14 meters per second for Naya.
C
The speed of the balloon is 37 meters per second for Alyssa and 23 meters per second for Naya.
D
The speed of the balloon is 14 meters per second for Alyssa and 23 meters per second for Naya.

Explanation

The balloon’s speed of 23 meters per second is measured relative to Alyssa as she tosses it. Since Alyssa is already running forward at 14 meters per second, Naya, who is standing still, sees the balloon move at 23 + 14 = 37 meters per second. So the supported statement is that the balloon’s speed is 23 meters per second for Alyssa and 37 meters per second for Naya.
