You join NASA and your first mission is to land on an unknown asteroid to record data. From the surface of the asteroid you launcha projectile with an initial speed of 80 m/s and notice that the projectile reaches a maximum height of 2500 m above the surface. By coincidence, 2500 m is also the radius of the asteroid. What is the acceleration of gravity on the surface of the asteroid?
