Task 1

Note: It is highly recommended that your read the Introduction before you start at this exercise.

In this task, t is the elapsed time between the two observations.

Choose a relation between the angular displacement, a, the time, t, and the angular velocity of the displacement, ω.

The angular velocity is measured in units of angle per unit time. It is important that this angle is measured in radians.

Choose a relation between the linear displacement, l, the time, t, and the velocity in the direction of the linear displacement, v_T. This velocity is called the tangential velocity.

The tangential velocity is measured in km/s.
