Deep Space 1 was a spacecraft powered by an engine that gave off xenon particles to change velocity.  It had a mass of 500 kg.  Which expression can be used to find the spacecraft's acceleration if its engine created a net force of 0.10 N?

• 0.10 N / 500 kg
• 500 kg * 0.10 N
• 500 kg / 0.10 N
• 500 kg + 0.10 N
