Question

Constants Part A To get a flat, uniform cylindrical satellito spinning at the correct rate, engineers fire four tangential rockets as shown in the figure (Figure 1). Suppose that the sateilite has a mass of 1400 kg and a radius of 3.3 m,and that the rockets each add a mass of 250 kg. What is the steady force required of each rocket if the satellite is to reach 32 rpm in 2.5 min, starting from rest? Express your answer to two significant figures and include the appropriate units.
