Question

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

A. The speed of the balloon is 23 m/s for Alyssa and 14 m/s for Naya.
B. The speed of the balloon is 37 m/s for Alyssa and 23 m/s for Naya.
C. The speed of the balloon is 14 m/s for Alyssa and 23 m/s for Naya.
D. The speed of the balloon is 23 m/s for Alyssa and 37 m/s for Naya.

Answer 1

Answer:   D

Explanation: I took the quiz

Answer 2

From Alyssa's point of view, the water balloon is at first at rest and then gets thrown with a velocity of 23m/s. Therefore the balloon will have a speed of 23m/s for Alyssa.

At the same time, Naya is watching, and she sees the balloon at the beginning moving at a speed of 14m/s along with Alyssa, and then pushed forward of other 23m/s. Therefore, from her point of view, the balloon will have a speed of 14+23 = 37m/s.

Hence, the correct answer is D) The speed of the balloon is 23 m/s for Alyssa and 37 m/s for Naya.
