Answer:
Work is the energy transferred to or from an object via the application of force along a displacement.
 
        
                    
             
        
        
        
Answer:
527 Hz
Solution:
As per the question:
Beat frequency of the player, 
Frequency of the tuning fork, f = 523 Hz
Now,
The initial frequency can be calculated as:


when 

when

But we know that as the length of the flute increases the frequency decreases
Hence, the initial frequency must be 527 Hz

Answer:
a) 4.2m/s
b) 5.0m/s
Explanation:
This problem is solved using the principle of conservation of linear momentum which states that in a closed system of colliding bodies, the sum of the total momenta before collision is equal to the sum of the total momenta after collision.
The problem is also an illustration of elastic collision where there is no loss in kinetic energy.
Equation (1) is a mathematical representation of the the principle of conservation of linear momentum for two colliding bodies of masses  and
 and  whose respective velocities before collision are
 whose respective velocities before collision are  and
 and  ;
;

where  and
 and  are their respective velocities after collision.
 are their respective velocities after collision.
Given;

Note that  =0 because the second mass
=0 because the second mass  was at rest before the collision.
 was at rest before the collision.
Also, since the two masses are equal, we can say that  so that equation (1) is reduced as follows;
 so that equation (1) is reduced as follows;

m cancels out of both sides of equation (2), and we obtain the following;

a) When  , we obtain the following by equation(3)
, we obtain the following by equation(3)

b) As  stops moving
 stops moving  , therefore,
, therefore,
