A student is trying to determine the minimum height from which to release a roller coaster cart so that the cart can complete the loop without falling off. Answer the questions for the case that the cart just barely loses contact with the surface at the top of the loop shown. Neglect backwards friction, drag and the size of the cart. Hint: Call the mass of the cart m. The mass will cancel! How many forces act on the cart at the top of the loop? What is the cart's acceleration at the top of the loop? m/s² What is the cart's speed at the top of the loop? m/s From what height must the cart be released? m A ot h 18m reference level

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.
