Either describe, sketch, or take a picture of a real system whose motion can be described by a single coordinate. At least one of the components must have mass, and at least one must have stiffness. For each of the components, indicate if it has mass, stiffness, and/or damping. Also explain if this is a rotational or translational system and why. The system you pick must be something you encounter in everyday life and may not be a system that has been discussed in class.

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
