Hello, Narrated Universe! In today's PHYSICS class, we will solve a very difficult question from ITA, which deals with OBLIQUE LAUNCH, KINEMATICS AND CONSERVATION OF LINEAR MOMENTUM (QUANTITY OF MOVEMENT). ITA 2017 From a horizontal plain, two particles are launched from opposite positions, following trajectories in the same vertical plane and colliding elastically at the point of their maximum altitude - the same for both. The first particle is launched at 30º and lands at 90º, also in relation to the ground, at a distance L from its launch. The second is launched at 60º in relation to the ground. Neglecting air resistance, determine: a) the ratio between the masses of the particles, b) the distance between the launch points and c) the horizontal distance traveled by the second particle. ????LEARN MORE ABOUT OUR WORK AND OUR COURSES: https://www.universonarrado.com.br/ ????Join our Telegram channel to access several study tips and free materials: https://t.me/universonarrado ????FOLLOW ME ON SOCIAL MEDIA: INSTAGRAM: / universonarrado FACEBOOK: / universonarrado TWITTER: / universonarrado
