#### Answer

The velocities are all different, but the kinetic energies are all the same.

#### Work Step by Step

Velocity is a vector that indicates both an object’s speed and its direction. The 3 objects are moving at the same speed of 5 m/s, but their directions differ, so they do not possess the same velocity.
We know that kinetic energy is $K=\frac{1}{2}mv^2$. The 3 objects have the same mass and the same speed, so they each have the same kinetic energy of 18.75 J. Kinetic energy is a scalar, and the direction of the velocity doesn’t affect it.
