Angular speed, acceleration and displacement

Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.

Angular Position

Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.

Question

Part A
What maximum height does the lighter object
reach after the system is released? [Hint: First
determine the acceleration of the lighter mass and
then its velocity at the moment the heavier one
hits the ground. This is its "launch" speed. Assume
the mass doesn't hit the pulley. Ignore the mass of
the cord.]
Express your answer using two significant
figures.

The two masses shown in the figure are each initially
1.8 m above the ground, and the massless
frictionless pulley is 4.8 m above the ground.
