2.7 Exercise 2

Avg difficulty 2.5

Observing a spacecraft land on a distant asteroid, scientists notice that the craft is falling at a rate of 5 m/s. When it is 100 m closer to the surface of the asteroid, the craft reports a velocity of 8 m/s. According to their data, what is the approximate gravitational acceleration on this asteroid?

  1. 0 m/s2
  2. 0.03 m/s2
  3. 0.20 m/s2
  4. 0.65 m/s2
  5. 33 m/s2
