Answer:

10432.19076 m

Explanation:

$\lambda$ = Wavelength = 660 nm

d = Diameter of pupils = 6 mm

s = Distance between lights = 1.4 m

L = Distance from observer

From Rayleigh's criteria we have

$1.22\lambda=dsin\theta$

As $\theta$ is small $sin\theta=\dfrac{s}{L}$

So, the equation becomes

$1.22\lambda=d\dfrac{s}{L}\\\Rightarrow L=\dfrac{ds}{1.22\lambda}\\\Rightarrow L=\dfrac{6\times 10^{-3}\times 1.4}{1.22\times 660\times 10^{-9}}\\\Rightarrow L=10432.19076\ m$

The car is 10432.19076 m from me

Travka [436]

Answer:

$0.62\:\mathrm{s}$

Explanation:

Since the universal SI unit for velocity is meters/second, let's convert ft/s to m/s:

$10\:\mathrm{ft/s}=3.048\:\mathrm{m/s}$

We can use the following kinematics equation to solve this question:

$v_f=v_i+at$

What we know:

The initial velocity, $v_i$ , is $3.048\:\mathrm{m/s}$

(physics concept) The final velocity must be equal in magnitude but opposite in direction to the initial velocity ( $v_f=-3.048\:\mathrm{m/s}$ )
Acceleration, $a$ , is acceleration due to gravity at about $9.8\:\mathrm{m/s}$

Solving for $t$ :

$-3.048=3.048+(-9.8t),\\-6.096=-9.8t,\\t=\frac{-6.096}{-9.8}\approx \boxed{0.62\:\mathrm{s}}$
