As per impulse momentum theorem we know that

now here we will have

t = 1.30 ms
m = 0.144 kg

now we need to find final speed using above formula


so final speed is given as above

Answer: 2. Solution A attains a higher temperature.
Explanation: Specific heat simply means, that amount of heat which is when supplied to a unit mass of a substance will raise its temperature by 1°C.
In the given situation we have equal masses of two solutions A & B, out of which A has lower specific heat which means that a unit mass of solution A requires lesser energy to raise its temperature by 1°C than the solution B.
Since, the masses of both the solutions are same and equal heat is supplied to both, the proportional condition will follow.
<em>We have a formula for such condition,</em>
 .....................................(1)
.....................................(1)
where:
 = temperature difference = temperature difference
- c= specific heat of the body 
<u>Proving mathematically:</u>
<em>According to the given conditions</em>
-  we have equal masses of two solutions A & B, i.e.  
- equal heat is supplied to both the solutions, i.e.  
- specific heat of solution A,  
- specific heat of solution B,  
 & & are the change in temperatures of the respective solutions. are the change in temperatures of the respective solutions.
Now, putting the above values


Which proves that solution A attains a higher temperature than solution B.
