The formula v=√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 30 feet. round your answer to the nearest hundredth.
a) 960 feet/sec
b) 43.82 feet/sec
c) 240 feet/sec
d) 350.54 feet/sec

  B)  43.82 feet/sec

Step-by-step explanation:

Fill in the number and evaluate:

  v = √(64×30) = √1920 ≈ 43.82 . . . . ft/s

Of course, √(64h) can be simplified to 8√h. You know that √30 lies between 5 and 6, so the velocity lies between 8·5 = 40 and 8·6 = 48. There is only one answer choice in that range.

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
