You are welcome!
This question is not very straight forward. It is considered as a challenging E Math question.
Please be reminded that stepbystep working is expected if you want to score full marks (including all method marks) for it.
Cheers!

Hi,
12 m/s^2 and m/s have different units. Cannot do conversion directly.
Maybe you can provide more information in the question?
Cheers

The answer is x+y=1. But I don't know how to get the answer.

Since the equation has EVEN power index, therefore, it is always positive.
In order to have the sum of (x+4)^50 + (y5)^100 = 0,
Therefore,
(x+4)^50 = 0 and (y5)^100 = 0
Hence,
x = 4 and y = 5
Therefore x + y = 1.
