Suppose the rocket is coming in for a vertical landing at the surface of the earth. The captain adjusts the engine thrust so that rocket slows down at the rate of 2.40m/s2 . A 6.00-kg instrument is hanging by a vertical wire inside a space ship.
I don't know if there are any relevant equations for this...[/B]
2. The attempt at a solution
So I figured that since the tension on the string in one direction is the weight and the force of gravity, and in the other direction it is the force of the captain slowing it down, I thought you could multiply 6 by 9.8, and then subtract 2.40.
How am I supposed to do it?
