A concept car includes a solid disk-shaped flywheel which can be spun up to store rotational kinetic energy. On demand, that stored energy can be converted into the car's translational kinetic energy. Suppose the flywheel has a mass of 380 kg, a radius of 0.4 m, and maximum rotational speed of 70 rev/s. Calculate the 1,593-kg car's maximum speed (starting from) rest if all of its kinetic energy comes from the flywheel.

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.
