His law exaplins/shows that the average distance of a planet from the Sun cubed is directly proportional to the orbital period squared.
Kinetic Energy is defined by 1/2 times the mass times the velocity squared.
KE = (1/2)mv2
The distance covered by the plane is 600 km
Explanation:
The motion of the plane is a uniform motion, so at constant velocity, therefore we can use the following equation

where
d is the distance covered
v is the velocity
t is the time interval considered
For the plane in this problem,
v = 400 km/h
t = 1.5 h
Substituting, we find the distance covered:
