To get a flat, uniform cylindrical satellite spinning at the correct rate, engineers fire four tangential rockets as shown in the figure (Figure 1). Suppose that the satellite has a mass of 3500 kg and a radius of 3.1 m, and that the rockets each add a mass of 250 kg. Part A What is the steady force required of each rocket if the satellite is to reach 28 rpm in 7.0 min , starting from rest? Express your answer to two significant figures and include the appropriate units. HÀ F = Value Units

A: Since the question have five more sub-parts. Here we will answer first three sub-parts.

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.
