Answer:
You wouldnt fall you would be sucked and you would lose all air supply and you lungs would pop
Explanation:
KE = 1/2mv^2
1/2(10.5)(9)^2
1/2(10.5)(81) = 425.25 J
The conservation of energy always holds true even when not clearly observable in machines that are less than 100% efficient. More often than not a machine will suffer energy losses (e.g. consider for a cooling fan: friction between the rotating blades, drag resistance in the air the fan is pushing around, resistance in the wire, and heat radiating/conducting away from the circuitry).
Answer:
Speed of the wreck after the collision is 65 km/h
Explanation:
When a car hits truck and sticks together, the collision would be totally inelastic. Since the both the vehicles locked together, they have the same final velocity.
Mass of car 
Mass of truck 
Initial speed of the car 
Initial speed of the truck 
The final velocity of the wreck will be
since final speed are same, 
Well simple the warm water then replaces the cold current that sinks to the ocean floor.
