A projectile moves along its path with a constant horizontal velocity. But its vertical velocity changes by -9.8 m/s each second of motion.
Vertical Motion of a Horizontal Projectile is Accelerated Motion (Free Fall) y Y – accelerated motion ay=-9.81 m/s2 (free fall) vy=0+(-9.81 m/s2 )t dy=H+(-4.905 m/s2 )t2 x A Horizontal Projectile is Half of a Parabola, and is the Addition of 2 Independent Motions y Ho...
