1. When an astronaut stands on scales prior to leaving Earth the scales record her weight as being 540 N.

A) What is the astronaut’s mass?

B) Halfway to her destination the engines fire, causing the scales on her spaceship to record her weight as 920 N. How fast is the spaceship accelerating?

C) After firing for several minutes, the rocket engines shut down and the spaceship begins to travel at a constant rate of 3500 m/s. What do the scales say she weighs now?

D) When she arrives at the planet she is traveling to, she measures her weight again. The gravitational acceleration (g) on this planet is 14.6 m/s2. How much does she weigh on this planet?
