They seem to cancel each other out which is odd
Answer:
The direction will be NE i.e North east.
Explanation:
From the question, it will be travelling in North east direction because the the negative X components in vector is in horizontal direction which is the Eastern direction when using the four cardinal points and the Y components, the positive is in North direction if you use the four cardinal points. Therefore, the vector with both X components and Y components will be travelling in Northeast direction.

Answer:
The second kinetic energy is 162 J.
Explanation:
Given that,
Mass, 
Velocity, 
Kinetic energy, 
Mass, 
Velocity, 
We need to find kinetic energy
. Kinetic energy is given by :

So,

So, the second kinetic energy is 162 J.
