Trajectories of ideal projectiles launched at different angles Plot of trajectories of projectiles launched at different elevation angles but the same speed of 10 m/s in a vacuum and uniform downward gravity of 10 m/s^2; t = time from launch, T = time of flight, R = range and H = highest point of trajectory (indicated with arrows); points are at 0.05 s intervals and length of their tails is linearly proportional to their speed; conceived and drawn by CMG Lee. t : 0.05 – 0.20 s t : 0.25 – 0.40 s t : 0.45 – 0.60 s t : 0.65 – 0.80 s t : 0.85 – 1.00 s t : 1.05 – 1.20 s t : 1.25 – 1.40 s t : 1.45 – 1.60 s t : 1.65 – 1.80 s t : 1.85 – 2.00 s 15° R:5.0m H:0.3m T:0.52s 30° R:8.7m H:1.2m T:1.00s 45° R:10.0m H:2.5m T:1.41s 60° R:8.7m H:3.7m T:1.73s 75° R:5.0m H:4.7m T:1.93s 90° R:0.0m H:5.0m T:2.00s 0 m 1 m 2 m 3 m 4 m 5 m 6 m 7 m 8 m 9 m 10 m
