Answer:
The 80 mph car
Because the formula says 1/2 mass but for the velocity it is squared
As per the question, the mass of meteorite [ m]= 50 kg
The velocity of the meteorite [v] = 1000 m/s
When the meteorite falls on the ground, it will give whole of its kinetic energy to earth.
We are asked to calculate the gain in kinetic energy of earth.
The kinetic energy of meteorite is calculated as -
Here, J stands for Joule which is the S.I unit of energy.
It’s will be B because the circuit had a open or close so if that doesn’t work than it’s because it’s open
