A water balloon is released from a stationary hot air balloon that is 100 meters above the ground as shown below. The water balloon is released with an initial velocity of 15.0 m/s at an angle of 30.0° from the horizontal. Calculate the magnitude of the velocity of the water balloon at the instant it lands.

• A. $55.0\mathrm{\ m}/\mathrm{s}$
• B. $46.7\mathrm{\ m}/\mathrm{s}$
• C. $35.3\mathrm{\ m}/\mathrm{s}$
• D. $25.8\mathrm{\ m}/\mathrm{s}$

Answer: (B)
