Just as you reach the top, the pole breaks at the base. The answer depends on the speed you have when you hit the ground. If you have negligible mass compared to the telephone pole, just work out the angular velocity of the telephone pole when it hits the ground. So, if you hang on to the pole you end up falling faster than if you'd fallen under the influence of gravity alone. Displacement is a vector.
Velocity is a vector.
Acceleration is a vector. As you might expect, angular displacement, angular velocity, and angular acceleration are all vectors, too. Every point on a rolling tire has the same angular velocity, and the only way to ensure that the direction of the angular velocity is the same for every point is to make the direction of the angular velocity perpendicular to the plane of the tire. To figure out which way it points, use your right hand. Stick your thumb out as if you're hitch-hiking, and curl your fingers in the direction of rotation.
