Two objects with the same mass move with the same speed but in opposite directions. Compare their kinetic energies. A.
Kinetic energies are equal.
B.
Kinetic energies are opposite in magnitude.
C.
Kinetic energy of the higher object is greater.
D.
Kinetic energy of the lower object is greater.

A.  Kinetic energies are equal.

Explanation:

The kinetic energy of the bodies will be equal since the mass and speed are the same.

Kinetic energy is the energy due to the motion of a body.

Mathematically;

           K.E  = m v²

m is the mass

v is the speed

 The kinetic energy is a scalar quantity with no regard for direction.
