Chapter 4 Simple Example: Projectile Motion Particle launched with velocity v x =10m/s, v y =49m/s How long does the projectile remain in the air? How far does the projectile go? What is the projectile velocity when it hits the ground? What is the maximum height of the projectile? 0 20 40 60 80 100 120 0 20 40 60 80 100 120 y (m) x (m) velocity components in red acceleration components in green Chapter 4 Maximizing Distance of Projectile Motion A projectile is launched over flat ground with velocity whose magnitude v. What angle should the initial velocity make with the horizontal to attain maximum distance?
