thank you very much brother. and i am so sorry to take your time.

then i must use this equation with total mass I =mr^2, is it right?

i tried it; when i calculate the inertia with rockets I=58750 and a=0.0105 so net torque=616.875, each rocket needs to provide a torque of 616.875/4=154.22 so F=30.84 but i is wrong:(:(

sorry. how can i find the angular accelaration using inertia?

i tried to do adding the inertias of rockets but it did not accept it and i have only one time to write the answer

Inertia=46250 , angular acceleration=0.0105, torque=485.63 and each torque of rocket=121.4 finally F=24.3 but it says it is wrong i think the problem is accelaration but i do not know another solution. i used this equation w=a.t, w: angular velocity, a:angular accelaration, t is time

sorry, i am in a hurry. i found the inertia of satellite I =0.5mr^2 and angular accelaration with this w = at = 33 rpm = 33*2*pi/60 = 3.455 rad/s. then calculate the torque Torque = I*a with this equation after that i divided it 4 to find each rocket torque. Torque = Frsin(angle between F,r)...

[SOLVED] A Problem About Satellite Homework Statement To get a flat, uniform cylindrical satellite spinning at the correct rate, engineers fire four tangential rockets as shown in the figure. If the satellite has a mass of 3700 kg, a radius of 5.0 m, and the rockets each add a mass of 250 kg...
