Answer:
red is not at the bottom. its density is 0.9 not 9!
also I don't need the brainlest thanks
 
        
                    
             
        
        
        
Answer:
How fast is it going? 29.4 Meters per second 
How far has it fallen? 44.1 meters
Explanation: Gravitional Acceleration: 9.8 meters per secnd squared!
 
        
             
        
        
        
The Hooke's law is a principal of physics that states that the force needed to extend or compress a spring by some distance x scales linearly with respect to that distance.
        
                    
             
        
        
        
Answer:
0.266 m
Explanation:
Assuming the lump of patty is 3 Kg then applying the principal of conservation of linear momentum, 
P= mv where p is momentum, m is mass and v is the speed of an object. In this case
 where sunscripts p and b represent putty and block respectively, c is common velocity.
 where sunscripts p and b represent putty and block respectively, c is common velocity.
Substituting the given values then
3*8=v(15+3)
V=24/18=1.33 m/s
The resultant kinetic energy is transferred to spring hence we apply the law of conservation of energy
 where k is spring constant and x is the compression of spring. Substituting the given values then
 where k is spring constant and x is the compression of spring. Substituting the given values then

 
        
             
        
        
        
The answer to this question is D or the last one
