Projectile Motion in x & y direction
In this sketch the red arrow shows the direction and magnitude of your throw. The sketch computes the length of time in the air, the slider lets you advance the clock, and the play button lets you see the movement.
This sketch allows you to make two different targets: one a garbage can on the ground and a seagull. Don't worry, no seagulls will be hurt even if you're deadly accurate. They're too quick, sadly.
