The image shows a person jumping from one railway cart to another. The carts are labeled as "A" and "B." The person is on cart A and is making a jump towards cart B.

A velocity vector is depicted, indicating that the jumper's speed is $ v = 4 \, \text{ft/s} $. The vector is shown with a direction making a right triangle, where the vertical component is labeled "5" and the horizontal component is labeled "12," suggesting the components of the velocity in the vertical and horizontal directions, respectively. The vector clearly illustrates the trajectory and speed of the jump.

This diagram could be used to illustrate concepts in physics such as projectile motion, vectors, and kinematics.
