1. A projectile is launched in a vertical plane, at an angle 0 with initial velocity vo. It must be caught in a frictionless circular tube of radius R in such a way that the trajectory of the projectile does not change abruptly when it enters the opening of the tube. What is the position (D, H) of the opening of the tube and the inclination of the tube? When the projectile enters the tube, the square of the speed of the projectile is equal to R.g.cos p. Data: vo = 8 m/s, 0 = 60°, R = 2 m. Ꮎ D H e R 1. A projectile is launched in a vertical plane, at an angle 0 with initial velocity vo.
