The formula v= square root 64h can be used to find the velocity, v, in feet per second, of an object that has fallen h feet. Find the velocity of an object that has fallen 75 feet. Round to the nearest tenth.
A. 6.9 ft/s
B. 69.2 ft/s
C. 69.4 ft/s
D. 69.3 ft/s
Is the answer D?
I agree.
With the equation v= √64h, you plug in 75 as h. Next, you multiply them to get 4,800. This would be √4,800.
Now, you solve that. the square root of 4.800 is 69.282032302755091741097853660235.
69.282032302755091741097853660235 is closer to the answer for D than any of the others, so D has to be the answer.
I hope this helps! :)
Well, well, well! It's time for some math fun, my friend! Let's see if your answer is correct.
Using the formula v = √(64h), we need to find the velocity when h = 75 feet.
v = √(64 * 75)
v = √(4800)
v ≈ 69.28 ft/s
Ah, so close! The correct answer is actually B, 69.2 ft/s. But hey, don't worry. Math can be a tricky little clown sometimes! Keep up the good work, and remember, laughter is the best solution to any problem!
To find the velocity of an object that has fallen 75 feet, we can substitute 75 for h in the formula v = √(64h).
v = √(64 * 75)
v = √(4800)
v ≈ 69.2820323 ft/s
Rounded to the nearest tenth, the velocity is approximately 69.3 ft/s.
Therefore, the correct answer is D. 69.3 ft/s.
To find the velocity of an object that has fallen 75 feet using the formula v = √(64h), you need to substitute h = 75 into the formula and calculate the result.
Step 1: Plug in the value of h into the formula:
v = √(64 * 75)
Step 2: Simplify the calculation inside the parentheses:
v = √(4800)
Step 3: Perform the square root calculation:
v ≈ 69.2820323
Step 4: Round the result to the nearest tenth:
v ≈ 69.3 ft/s
Based on the calculations, the velocity of an object that has fallen 75 feet is approximately 69.3 ft/s. Therefore, your answer is D.
