A cat of mass 4.0kg increases its angular speed by py pulling in all it's limbs. It launches from a vertical tree trunk with its limbs spread out wide. It's initial angular speed on launch is ω = 2.0rad/s about it's rotation axis, its limbs are spread wide and its rotation axis is horizontal, parallel to its spine. It pulls in its limbs immediately after launch such that its limbs are kept in close for all the time it is in the air. It is in the air for 1.5 secs. Through what angle does the cat turn in the air? Take the cat to be two point-masses each of mass 2m, represented by the folloing model about a horizontal rotation axis (out of page) where at launch, r = rl = 10cm, and in the air, r = ra = 5.0cm
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.
