when a stone falls freely, the time taken to hit the ground varies as the square root of the distance fallen. If it takes four s
Eva8 [605]

Answer:

The stone would take approximately 10.107 seconds to fall 500 meters.

Step-by-step explanation:

According to the statement of the problem, the following relationship of direct proportionality is built:

t \propto y^{1/2}

t = k\cdot t^{1/2}

Where:

t - Time spent by the stone, measured in seconds.

y - Height change experimented by the stone, measured in meters.

k - Proportionality constant, measured in \frac{s}{m^{1/2}}.

First, the proportionality constant is determined by clearing the respective variable and replacing all known variables:

k = \frac{t}{y^{1/2}}

If t = 4\,s and y=78.4\,m, then:

k = \frac{4\,s}{(78.4\,m)^{1/2}}

k \approx 0.452\,\frac{s}{m^{1/2}}

Then, the expression is t = 0.452\cdot y^{1/2}. Finally, if y = 500\,m, then the time is:

t = 0.452\cdot (500\,m)^{1/2}

t \approx 10.107\,s

The stone would take approximately 10.107 seconds to fall 500 meters.

Step-by-step explanation:

given \\ (x +  \frac{1}{x} ) = 7 \\ now \\ (x +  \frac{1}{x} ) ^{2}   \\ (7) ^{2} (given) \\ 49 \\ again \\  {x}^{2}  + ( \frac{1}{x} ) ^{2}  \\ (x  +   \frac{1}{x}) ^{2}  - 2 \times x \times  \frac{1}{x}  \\ (7) ^{2}  - 2 \\ 49 - 2 \\ 47
