Answer:
bird's speed  = 4.58 m/s 
Explanation:
given data 
mass of bird mb = 300 g
velocity of bird vb = 5.7 m/s
mass of insect mi = 10 g
velocity of insect vi = - 29 m/s
solution
here momentum of system is constant 
we apply here conservation of momentum so 
mb × v + mi × v = mb × vb + mi × vi   ....................1
v ( mb + mi ) = mb × vb + mi × vi  
put here value and we get 
v ( 300 + 10 ) = { 300 × 5.7 }  +  { 10 × (-29) } 
v =  
  
v = 4.58 m/s 
 
        
             
        
        
        
Answer:
The magnitude of acceleration is 3 m/s^2.
Explanation:
The net force along North-South direction is 18-24=-6 N.
The net force along East-West direction is 16-16=0 N
The net magnitude of force is square root of (-6)^2+0^2 which is 6 N.
By Newton's Second law, 
Force F=ma 
Therefore acceleration a=F/m
                                        a=6/2 
                                        a=3 m/s^2

Answer:
Compression in the spring, x = 3.7 cm
Explanation:
It is given that,
Mass of the book, m = 1.6 kg
It can be assumed the spring constant of the spring is, k = 840 N/m
As the book moves down, the change in potential energy of the book is converted to spring potential energy of compression. The mathematical expression is as follows :


 
  
x = 0.037 meters
or
x = 3.7 cm
So, the spring is compressed to a distance of 3.7 cm. Hence, this is the required solution.
