Answer:
A body having uniform velocity has zero acceleration because
there is not change in velocity.
 
        
                    
             
        
        
        
-- First, we have to decide how to handle the two resistors.
The effective resistance of resistors in series is the sum 
of their individual resistances.  That is, they act like a single 
resistor, whose resistance is the sum of all of them.
So in this question, the 4.0 ohms and the 7.5 ohms act like a 
single resistor of 11.5 ohms.
-- The current in the circuit is
                       (the supply voltage) / (the total resistance)
                   =                (9.0 volts)  /  (11.5 ohms)
                   =                      0.783... Ampere        (rounded)
        
                    
             
        
        
        
To solve this problem it is necessary to apply the equations related to the conservation of momentum. Mathematically this can be expressed as

Where,
 = Mass of each object
= Mass of each object
 = Initial velocity of each object
 = Initial velocity of each object 
 = Final Velocity
= Final Velocity 
Since the receiver's body is static for the initial velocity we have that the equation would become



Therefore the velocity right after catching the ball is 0.0975m/s
