# One of the first ion engines on a commercial satellite used Xenon as a propellant and could eject the ionized gas at a rate of 3.03 × 10−6 kg/s with an exhaust speed of 3.04 × 104 m/s. What instantaneous thrust could the engine provide?

To determine
The instantaneous thrust of a rocket engine.

Explanation

Given Info: The rate of change of mass is Î”M/Î”t=3.03Ã—10âˆ’6kg/s and exhaust speed of an engine is ve=3.04Ã—104m/s .

Explanation:

The expression for thrust is

T=|veÎ”mÎ”t| (1)

Substitute 3.03Ã—10âˆ’6â€‰kg/s for Î”M/Î”t and 3
