Explanation:
i think this is right i dont know tho
The amount of energy before and after any energy transformations remain the same because energy cannot be created or destroyed. From the law conservation of energy; any time energy is transferred between two objects, or converted from one form into another, no energy is created and none is destroyed. The total amount of energy involved in the process remains the same.
Answer:
The speed of object B is 2 times of speed of object A.
Explanation:
Given that,
Kinetic energy of object A = 25 J
Mass of object B 
Work done = -20 J
We need to calculate the factor of the speed of the object
Suppose the final kinetic energy is same for both object.


Put the value into the formula




Hence, The speed of object B is 2 times of speed of object A.
