figure 1.Position of a ball forsome time interval​

Sagot :

Answer:

x(t) = xo + vox t + ½ ax t2 . y(t) = yo + voy t + ½ ay t2 . These equations tell you everything about the motion of a projectile (neglecting air resistance). If you know the conditions (yo , vox , voy ) at t = 0 , then these equations tell you the position (x(t) , y(t)) of the projectile for all future time t > 0.
