You have a grindstone (a disk) that is 150.92 kg, has a 0.365-m radius, and is turning at 59.859 rpm, and you press a steel axe against it with a radial force of 46.387 N. Assuming the kinetic coefficient of friction between steel and stone is 0.582. How many turns will the stone make before coming to rest? Round your answer to the third decimal place.
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.
