Projecto shot horizontally:
ax =0 ay = - 9.8 m/s2
vx = constant vy changingΔdx = range Δdx = height
Use the formulas:
Δdx= vx Δt Δdy= vy Δt + ½ ay Δt2
If you can find the Δt in x direction, then transfer it in the y direction and find the height.
If you can’t find Δt in the x-direction calculate it in the y-drection, and then transfer it to y-direction to find the range.
