A satellite of mass 59.0 Kg is being pulled out of orbit by 450.0?
1- A satellite of mass 59.0 Kg is being pulled out of orbit by 450.0 Netwons of gravity. Small thrusters are used to maneuver the satellite back to its orbite.
a)What thrust would cause the satellite to move with a constant velocity?

Find the accerleration of the satellite in response to the following thrusts:
b) 205 N up c) 205 N down d) 205 N right.

I found the a that is 450 N. However, I do not for b-c-d could someone help me please

b) 205-450= 59 a a=-4.9 m/s^2 the acceleration down.
c) -205-450=59 a a=-13.1 m/s^2 a goes down
d)205-450=59 a=-4.2m/s^2 a goes down too

You really need to start showing your attempt at a solution before getting more help here.

You must know something about the relation between force and acceleration.

Okay, that's the sort of thing you need to do when you first post the question. Or rather, when you post questions in the future.

(b) and (c) are pretty close. Looks like you just used the wrong mass when you calculated a.

(d) Not right. Remember that acceleration is a vector. How do vectors get added?
