To solve this problem, we need to use the principles of projectile motion.Given information:- The height of the roof is 17 meters.- The initial velocity of the water balloons is 21 m/s (horizontally).Step 1: Calculate the time it takes for the water balloon to fall to the ground.Using the equation of motion for vertical motion:h = (1/2)gt^2Where:h = height (17 m)g = acceleration due to gravity (9.8 m/s^2)t = timeRearranging the equation to solve for time:t = √(2h/g)t = √(2 × 17 m / 9.8 m/s^2)t = 1.85 secondsStep 2: Calculate the horizontal distance traveled by the water balloon.Using the equation of motion for horizontal motion:x = v × tWhere:x = horizontal distancev = initial horizontal velocity (21 m/s)t = time (1.85 seconds)x = 21 m/s × 1.85 sx = 39.06 metersTherefore, the correct answer is 39.06 meters.
