Answer:
10,454,400 sec
Step-by-step explanation:
1Day=24hr
1hr=60min
1min=60sec
121 days=121*24*60*60=10,454,400sec
 
        
             
        
        
        
Assuming Earth's gravity, the formula for the flight of the particle is: 
s(t) = -16t^2 + vt + s = -16t^2 + 144t + 160. 
This has a maximum when t = -b/(2a) = -144/[2(-16)] = -144/(-32) = 9/2. 
Therefore, the maximum height is s(9/2) = -16(9/2)^2 + 144(9/2) + 160 = 484 feet. 
 
        
                    
             
        
        
        
Answer:
I eat 3/10 of the coconut and my friend eats 1/5 which is 2/10.
We both eat 3/10 + 2/10 which is 1/2 of the coconut.
