distance - Calculate time to reach top of the trajectory of a projectile -
i have below information gravity, thrust, initial x, y , initial velocities. how calculate
1. time reach top of projectile 2. horizontal displacement during time
"grav": 0.7, "thrust": 10.5, "me": { "x": 0, "y": 180, "vx": 4, "vy": 0 }
so far have tried formula calculate vertical displacement (reference here)
for horizontal displacement, used t*vx0
;
if initial vertixal velocity(vy) zero, assuming gravity on y direction, how object ever going go reach top?
generally thrown objects reach top when vy = 0 when t= vy/grav, , x position = t * vx.
