Answer:

The time is $t = 8.78 \ s$

Explanation:

From the question we are told that

The initial height of the eye is $h _1 = 20 \ cm = 0.2 \ m$

The height of the eye when you jumped up is $h_2 = 150 \ cm = 1.5 \ m$

An illustration of this question is shown on the first uploaded image

Generally the radius of the earth is $R = 6.38*10^{6} \ m$

Now from the diagram first sun means first time you saw the sun and the second sun means second time you saw the sun then

H is the height increase when you quickly stood up which is mathematically evaluated as

$H = h_2 -h_1$

$H = 1.5 - 0.2$

$H = 1.3 \ m$

Also $\theta$ i the angular displacement between the first and second position and from geometry it is also the angle at one of the sides of the right angle triangle

Applying Pythagoras theorem

$(R+H)^2 = K^2 + R^2$

=> $R^2 + H^2 + 2RH = K^2 + R^2$

Now given that H is very small compared to R the we ignore $H^2$

So

$R^2 + 2RH = K^2 + R^2$

=> $K = \sqrt{2RH}$

=> $K = \sqrt{2 * 6.38*10^6 * 1.3 }$

=> $K = 4073 \ m$

Now the $\theta$ is mathematically evaluated using SOHCAHTOA as follows

$tan \theta = \frac{K}{R}$

$\theta = tan^{-1}[ \frac{K}{R}]$

=> $\theta = tan^{-1}[ \frac{ 4073}{6.38*10^{6}}]$

=> $\theta = 0.0366^o$

Generally

$1 \revolution\ around \ the\ earth = 24 \ hours = 86400 \ seconds = 360 ^o$

So

$\frac{\theta}{360} = \frac{t}{86400}$

=> $\frac{0.0366}{360} = \frac{t}{86400}$

=> $t = 8.78 \ s$

At t = 0, object A is dropped from the roof of a building. At the same instant, object B is dropped from a window 10 m below the

dsp73

Answer:

Explanation:

Given two objects are dropped simultaneously

Object A is 10 m higher than object B therefore

Distance covered by object A is given by

$y_a(t)$ is given by

$y=ut+\frac{1}{2}at^2$

where y=displacement

u=initial velocity

a=acceleration

t=time

$y_a(t)=0+0.5gt^2--1$

for object B

$y_b(t)=0+0.5gt^2--2$

Subtract 1 and 2 we get

$y_a(t)-y_b(t)=0$

i.e. they will travel equal distance in equal time and distance between them remain 10 m until object B hits the ground
