).A water-balloon dropped from a 38th-floor window hits the ground at86 m/s. What is its speed in ft/s? Round your answer to the nearest ft/s.(a)26 ft/s(b)29 ft/s(c)257 ft/s(d)282 ft/s
86 m/s * 3.28ft/m = ____ ft/s
To convert the speed from meters per second to feet per second, we can use the conversion factor 1 meter = 3.281 feet.
Given that the speed of the water balloon is 86 m/s, we can use the following steps to convert it to ft/s:
1. Multiply the speed in meters per second by the conversion factor:
86 m/s * 3.281 ft/m = 282.166 ft/s (rounded to three decimal places).
Therefore, the speed of the water balloon in ft/s is approximately 282 ft/s.
The correct answer choice is (d) 282 ft/s.
To convert the speed from m/s to ft/s, we need to use the conversion factor of 1 m/s = 3.281 ft/s.
Let's calculate the speed in ft/s:
Speed (ft/s) = Speed (m/s) × Conversion Factor
Given that the speed of the water-balloon is 86 m/s, we can calculate:
Speed (ft/s) = 86 m/s × 3.281 ft/s
Speed (ft/s) ≈ 282.266 ft/s
Rounding this answer to the nearest ft/s, we get 282 ft/s.
Therefore, the correct answer is (d) 282 ft/s.
