<span>Before all let's just convert Km/s into m/s :
             
2.41 km/s = 2410m/s\

To solve the second part
     
First we have to find Vy Vy = 2410 m/s * sin 61.5 = 2410 m/s * 0.8788 =2117.908 m/s.
       
When the shell reaches it's maximum height the vertical velocity component will be zero
 
based on that theorem let's apply linear motion equation
                           
V = u + at
                           
0 = 2117.908 m/s - 9.8 m/S^2 * (t)
                         
t = 216.1130 s
 
As the shell has to go upward and comes back to earth the shell will require a same amount of time in order to reach earth again so the total time that shell will spend on the air will be
                     
<span>2*t = 432.226 s 


I hope my answer has come to your help. Have a nice day ahead and may God bless you always!</span></span>

The number of tourists at the beach per weekend in July was 55,000, In November, the number of tourists per weekend was 18,000.
Ganezh [65]

Answer:

The percentage change from July to November is 67.27 %

Step-by-step explanation:

Given as :

The number of tourists at the beach per weekend in the month of July = x_1 = 55,000

The number of tourists at the beach per weekend in the month of November = x_2 = 18,000

Let the percentage change from July to November = A %

Or,  % decrease change = \dfrac{\tetxtrm new value - \textrm old value}{\textrm old value} × 100

So , A % = \dfrac{\tetxtrm [tex]x_2   - \textrm  x_1 }{\textrm  x_1 }[/tex] × 100

or, A % = \frac{55000 - 18000}{55000} × 100

Or, A % = \frac{37000}{55000} × 100

Or, A  = 67.27 %

So percentage change between two months = 67.27 %

Hence The percentage change from July to November is 67.27 % Answer
