Answer:
Explanation:
Given
mass of ball is m
Spring constant is k
If a ball is undergoing a SHM motion then the total energy associated with it is
Total Energy 
where A=maximum Amplitude
Elastic Potential Energy of the system at any moment is given by

where x=compression in the spring
moment at which kinetic(K) and potential energy(U) are equal
i.e. 
Total energy




i.e. at x=0.707 A kinetic energy and potential energy are equal
Answer:
Reflection
Explanation:
this because water reflects light
It is B since they are traveling at the same speed one is positive so the other had to be negative hope this helps;)))))
