Consider a projectile fired directly upward in a vacuum. At t = 0 (seconds), the projectile has x-coordinate (in meters) of 0.0 (it is on the ground). It is fired directly upward with an unknown initial velocity v0. The gravitational acceleration is a strange function of altitude and can be described by g(x) = -9.8/(1+0.001x). However, at exactly t = 20, the projectile returns to x = 0.Use the shooting method to determine the initial upward velocity of the projectile. Which of the following numbers best represents that initial velocity (m/s)?
