Yes, the water in the cup have the same average kinetic energy as the ocean, because I focus on the word 'average'. However the cup of water have less INTERNAL energy than the ocean.

Answer:
15.75 m/s
Explanation:
v = Velocity of the combined mass of astronaut and tools = 1.8 m/s
= Mass of astronaut = 124 kg
= Mass of tools = 16 kg
= Velocity of astronaut = 0
= Velocity of tools
As linear momentum is conserved

The velocity of the tools is 15.75 m/s
