The kinetic energy of the electron is
where
is the mass of the electron and v its speed. Since we know the value of the kinetic energy, 
, we can find the value of the speed v:

Explanation:
We have,
Speed of plane a is 900 km/h
Plane b is moving at a rate of
It is required to find which plane is faster. To find which plane is faster, we need to compare their speeds.
Speed of a plane a is 900 km/h and that of plane b is 50 km/h. So, we can say that plane a is moving faster.
