Answer: 
Step-by-step explanation:
Given: Mass of baseball=0.145 kg
Speed of baseball=40 meters per second
Also it is given that The kinetic energy (in joules) of a moving object can be calculated from the expression  , where 'm' is the mass of the object in kilograms and 'v' is its speed in meters per second.
 , where 'm' is the mass of the object in kilograms and 'v' is its speed in meters per second.
Thus, the kinetic energy of baseball=

 
        
                    
             
        
        
        
<u>Answer:</u>
The length of the person’s shadow is 5.7ft
<u>Explanation:</u>
Length of the flagpole =a= 35ft
Length of the shadow of the flagpole= b=50ft
Length of the person=c= 4ft
Suppose the length of the person’s shadow is=d
According to the  rules of trigonometry



35d=200
d=
d=5.7ft  
Hence, The length of the person’s shadow is 5.7ft.
 
        
             
        
        
        
Angles in a triangle adds up to 180
All you do it 59+69 which is 128
Then you do 180-128 the answer is 52
