a constant angular acceleration 2.50 [rad/s2]. A. How much time does it take to reach an angular velocity of 50.0 [rad/s] starting from rest? B. Through how many revolutions does the blade turn in this time interval? C. What are the tangential acceleration and tangential speed of an ant sitting on the blade 30.0 [cm] from the axis of rotation during the end of this interval? D. What is the moment of inertia of the ant if its mass is 50.0[g]? E. What is the rotational kinetic energy of the ant?
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.
Hoping for complete solutions since I’m having a hard time with this. Pls skip if unsure or not willing to answer the subitems (these are all connected for one item). Thanks in advanced!
