1. A rubber ball is tied to a 3-meter string and revolves around an erect pole at a velocity of 7.5 m/s every five (5) seconds. What is the ball’s angular acceleration in radians per square second?
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.

2. A man used his prototype invention, the 3D Maneuver Gear, to navigate his hometown. He maintained his velocity of 96 m/s as he swung on top of a 15-storey building, his anchors placed 250 m away, at the height of 325 m. He swung 52.43° to propel himself up, then 35° to the West to reach his endpoint. How fast is he in all 3D components?
