On planet X (gX = 20.00 m/s2), without atmosphere, a projectile has been fired from the ground, at the angle θ0 and initial speed v0. After time t, the projectile has travelled horizontal distance x, and its height is h ( the values of t=0.40, x=5.60, and y=2.93). Find θ0 and v0.

A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. The same projectile was then fired in the same way toward a wall that is a horizontal distance (d) m from where the projectile was fired, and the projectile (as it's going down) hit the wall. If the wall were slightly farther from where the projectile was launched (the projectile...
