Answer:
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.
From the diagram we have that
Therefore the direction is 30° from east of south
