Answer:


Explanation:
= Mass of first object
= Mass of second object
v = Speed of both objects
= Combined velocity
The ratio of final kinetic energy to initial kinetic energy will be

The ratio is 
As the linear momentum is conserved

Divide by
on both sides

The ratio of mass is 
Is Newton runs at the same average speed then the answer would be 40/5.79 = 6.908 m/s
